## Note that this doesn't just cater to obsosete pre-3.x GCC compilers.

## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

\`configure' configures rdfind 1.5.0 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/rdfind]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]

Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-silent-rules less verbose build output (undo: "make V=1")
--disable-silent-rules verbose build output (undo: "make V=0")
--enable-dependency-tracking
do not reject slow dependency extractors
--disable-dependency-tracking
speeds up one-time build
--enable-debug enable debug printouts in program (default=no)
--disable-assert turn off assertions
--disable-largefile omit support for large files
--enable-warnings enable compiler warnings (default=no)
Some influential environment variables:
CXX C++ compiler command
CXXFLAGS C++ compiler flags
LDFLAGS linker flags, e.g. -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
CXXCPP C++ preprocessor
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
Report bugs to the package provider.

Oops!
Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard:
Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message. This
can help us improve future automake versions.

Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: .
If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.

20060603
What happens when items are being removed because of duplicate inode,
is the correct precedence preserved?
20060315: it removes depending on priority and depth, as it should.
20060603
maybe a tip howto combine with find and xargs.

If you are building from a tarball and have nettle installed system wide,
building and installing should be as easy as
./configure
make
make install
If you are building from git you may need to install autotools.
On a debian or ubuntu system, please install the following packages:
nettle-dev build-essential
after that,
./bootstrap.sh && ./configure && make
should do the trick

.SH NAME
rdfind \- finds duplicate files
.SH SYNOPSIS
.B rdfind [ options ]
.I directory1 | file1
.B [
.I directory2 | file2
.B ] ...
.SH DESCRIPTION
.B rdfind
finds duplicate files across and/or within several directories. It calculates
checksum only if necessary.
rdfind runs in O(Nlog(N)) time with N being the number of files.
If two (or more) equal files are found, the program decides which of
them is the original and the rest are considered duplicates. This
is done by ranking the files to each other and deciding which has the
highest rank. See section RANKING for details.
By default, no action is taken besides creating a file with the
detected files and showing the possible amount of saved space.
If you need better control over the ranking than given, you can use
some preprocessor which sorts the file names in desired order and then
run the program using xargs. See examples below for how to use find
and xargs in conjunction with rdfind.
To include files or directories that have names starting with -, use
rdfind ./- to not confuse them with options.
.SH RANKING
Given two or more equal files, the one with the highest rank is
selected to be the original and the rest are duplicates. The rules of
ranking are given below, where the rules are executed from start until
an original has been found. Given two files A and B which have equal
size and content, the ranking is as follows:
If A was found while scanning an input argument earlier than B, A
is higher ranked.
If A was found at a directory depth lower than B, A is higher ranked
(A is closer to the root).
if A and B are found during scanning of the same input argument and share
the same directory depth, the one that ranks highest depends on if
deterministic operation is enabled. This is on by default, see option
\fB-deterministic\fR). If enabled, which one ranks highest is
unspecified but deterministic. If disabled, the one that was reported
first from the file system is highest ranked.
.SH OPTIONS
Searching options etc:
.TP
.BR \-ignoreempty " " \fItrue\fR|\fIfalse\fR
Ignore empty files. Setting this to true (the default) is equivalent to
-minsize 1, false is equivalent to -minsize 0.
.TP
.BR \-minsize " "\fIN\fR
Ignores files with less than N bytes. Default is 1, meaning empty files
are ignored.
.TP
.BR \-maxsize " "\fIN\fR
Ignores files with N bytes or more. Default is 0, which means this check
is disabled.
.TP
.BR \-followsymlinks " " \fItrue\fR|\fIfalse\fR
Follow symlinks. Default is false.
.TP
.BR \-removeidentinode " " \fItrue\fR|\fIfalse\fR
Removes items found which have identical inode and device ID. Default
is true.
.TP
.BR \-checksum " " \fImd5\fR|\fIsha1\fR|\fIsha256\fR
What type of checksum to be used: md5, sha1 or sha256. The default is
sha1 since version 1.4.0.
.TP
.BR \-deterministic " " \fItrue\fR|\fIfalse\fR
If set (the default), sort files of equal rank in an unspecified but
deterministic order. This makes the behaviour independent of in which
order files are listed when querying the file system.
.PP
Action options:
.TP
.BR \-makesymlinks " " \fItrue\fR|\fIfalse\fR
Replace duplicate files with symbolic links. Default is false.
.TP
.BR \-makehardlinks " " \fItrue\fR|\fIfalse\fR
Replace duplicate files with hard links. Default is false.
.TP
.BR \-makeresultsfile " " \fItrue\fR|\fIfalse\fR
Make a results file in the current directory. Default is true. If the
file exists, it is overwritten. This does not affect whether items are
deleted. See -dryrun for how to disable deletions.
.TP
.BR \-outputname " " \fIname\fR
Make the results file name to be "name" instead of the default
results.txt.
.TP
.BR \-deleteduplicates " " \fItrue\fR|\fIfalse\fR
Delete (unlink) files. Default is false.
.PP
General options:
.TP
.BR \-sleep " " \fIX\fRms
Sleeps X milliseconds between reading each file, to reduce
load. Default is 0 (no sleep). Note that only a few values are
supported at present: 0,1-5,10,25,50,100 milliseconds.
.TP
.BR \-n ", " \-dryrun " " \fItrue\fR|\fIfalse\fR
Displays what should have been done, don't actually delete or link
anything. Default is false.
.TP
.BR \-h ", " \-help ", " \-\-help
Displays a brief help message.
.TP
.BR \-v ", " \-version ", " \-\-version
Displays the version number.
.SH EXAMPLES
.TP
Search for duplicate files in the home directory and a backup directory:
.B rdfind ~ /mnt/backup
.TP
Delete duplicates in a backup directory:
.B rdfind -deleteduplicates true /mnt/backup
.TP
Search for duplicate files in directories called foo:
.B find . -type d -name foo -print0 |xargs -0 rdfind
.SH FILES
.I results.txt
(the default name is results.txt and can be changed with option outputname,
see above) The results file results.txt will contain one row per duplicate file
found, along with a header row explaining the columns.
A text describes why the file is considered a duplicate:
DUPTYPE_UNKNOWN some internal error
DUPTYPE_FIRST_OCCURRENCE the file that is considered to be the original.
DUPTYPE_WITHIN_SAME_TREE files in the same tree (found when processing
the directory in the same input argument as the original)
DUPTYPE_OUTSIDE_TREE the file is found during processing another input
argument than the original.
.SH ENVIRONMENT
.SH DIAGNOSTICS
.SH EXIT VALUES
0 on success, nonzero otherwise.
.SH BUGS/FEATURES
When specifying the same directory twice, it keeps the first
encountered as the most important (original), and the rest as
duplicates. This might not be what you want.
The symlink creates absolute links. This might not be what you
want. To create relative links instead, you may use the symlink (2)
command, which is able to convert absolute links to relative links.
Older versions unfortunately contained a misspelling on the word
occurrence. This is now corrected (since 1.3), which might affect
user scripts parsing the output file written by rdfind.
.SH SECURITY CONSIDERATIONS
Avoid manipulating the directories while rdfind is reading.
rdfind is quite brittle in that case. Especially, when deleting
or making links, rdfind can be subject to a symlink attack.
Use with care!

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an

now requires a c++11 capable compiler
1.3.5
Capitalization of bytes is now more correct in the console output.
It is unlikely this affects usage, unless the user actually parses the
output of the command rather than the results file.
sha1 was always selected over md5, even if the user specified md5
on the commandline. This is now fixed.
1.3.1
now builds with gcc 4.7
1.3.0
Spelling of OCCURRENCE is now correct. This might affect user scripts
parsing the output file (results.txt).
1.2.3+
fixed bug with failure to read files given directly on command line
added debug support in configure script
