.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIlatexdiff-vc\fR is a wrapper script that applies \fIlatexdiff\fR to a
file, or multiple files under version control (\s-1CVS, RCS\s0 or \s-1SVN\s0), and optionally runs the
sequence of \f(CW\*(C`latex\*(C'\fR and \f(CW\*(C`dvips\*(C'\fR or \f(CW\*(C`pdflatex\*(C'\fR commands necessary to
produce pdf or postscript output of the difference tex file(s). It can
also be applied to a pair of files to automatise the generation of difference
file in postscript or pdf format.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-\-rcs\fR, \fB\-\-svn\fR, \fB\-\-cvs\fR, or \fB\-\-git\fR" 4
.IX Item "--rcs, --svn, --cvs, or --git"
Set the version system. 
If no version system is specified, latexdiff-vc will venture a guess.
.Sp
latexdiff-cvs and latexdiff-rcs are variants of latexdiff-vc which default to 
the respective versioning system. However, this default can still be overridden using the options above.
.IP "\fB\-r\fR, \fB\-r\fR \fIrev\fR or \fB\-\-revision\fR, \fB\-\-revision=\fR\fIrev\fR" 4
.IX Item "-r, -r rev or --revision, --revision=rev"
Choose revision (under \s-1RCS, CVS, SVN\s0 or \s-1GIT\s0). One or two \fB\-r\fR options can be
specified, and they result in different behaviour:
.RS 4
.IP "\fBlatexdiff-vc\fR \-r \fIfile.tex\fR ..." 4
.IX Item "latexdiff-vc -r file.tex ..."
compares \fIfile.tex\fR with the most recent version checked into \s-1RCS.\s0
.IP "\fBlatexdiff-vc\fR \-r \fIrev1\fR \fIfile.tex\fR ..." 4
.IX Item "latexdiff-vc -r rev1 file.tex ..."
compares \fIfile.tex\fR with revision \fIrev1\fR.
.IP "\fBlatexdiff-vc\fR \-r \fIrev1\fR \-r \fIrev2\fR \fIfile.tex\fR ..." 4
.IX Item "latexdiff-vc -r rev1 -r rev2 file.tex ..."
compares revisions \fIrev1\fR and \fIrev2\fR of \fIfile.tex\fR.
.Sp
Multiple files can be specified for all of the above options. All files must have the
extension \f(CW\*(C`.tex\*(C'\fR, though.
.IP "\fBlatexdiff-vc\fR  \fIold.tex\fR \fInew.tex\fR" 4
.IX Item "latexdiff-vc old.tex new.tex"
compares two files.
.RE
.RS 4
.Sp
The name of the difference file is generated automatically and
reported to stdout.
.RE
.IP "\fB\-d\fR or \fB\-\-dir\fR  \fB\-d\fR \fIpath\fR or \fB\-\-dir=\fR\fIpath\fR" 4
.IX Item "-d or --dir -d path or --dir=path"
Rather than appending the string \f(CW\*(C`diff\*(C'\fR and optionally the version
numbers given to the output-file, this will prepend a directory name \f(CW\*(C`diff\*(C'\fR 
to the
original filename, creating the directory and subdirectories should they not exist already.  This is particularly useful in order to clone a
complete directory hierarchy.  Optionally, a pathname \fIpath\fR can be specified, which is prepended instead of \f(CW\*(C`diff\*(C'\fR.
.IP "\fB\-\-fast\fR or \fB\-\-so\fR" 4
.IX Item "--fast or --so"
Use \f(CW\*(C`latexdiff\-fast\*(C'\fR or \f(CW\*(C`latexdiff\-so\*(C'\fR, respectively (instead of \f(CW\*(C`latexdiff\*(C'\fR).
.IP "\fB\-\-ps\fR or \fB\-\-postscript\fR" 4
.IX Item "--ps or --postscript"
Generate postscript output from difference file.  This will run the
sequence \f(CW\*(C`latex; latex; dvips\*(C'\fR on the difference file (do not use
this option in the rare cases, where three \f(CW\*(C`latex\*(C'\fR commands are
required if you care about correct referencing).  If the difference
file contains a \f(CW\*(C`\ebibliography\*(C'\fR tag, run the sequence \f(CW\*(C`latex;
bibtex; latex; latex; dvips\*(C'\fR.
.IP "\fB\-\-pdf\fR" 4
.IX Item "--pdf"
Generate pdf output from difference file using \f(CW\*(C`pdflatex\*(C'\fR. This will
run the sequence \f(CW\*(C`pdflatex; pdflatex\*(C'\fR on the difference file, or
\&\f(CW\*(C`pdflatex; bibtex; pdflatex; pdflatex\*(C'\fR for files requiring bibtex.
.IP "\fB\-\-force\fR" 4
.IX Item "--force"
Overwrite existing diff files without asking for confirmation. Default 
behaviour is to ask for confirmation before overwriting an existing difference
file.
.IP "\fB\-\-help\fR or \fB\-h\fR" 4
.IX Item "--help or -h"
Show help text
.IP "\fB\-\-version\fR" 4
.IX Item "--version"
Show version number
.PP
All other options are passed on to \f(CW\*(C`latexdiff\*(C'\fR.

.SH "PORTABILITY"
.IX Header "PORTABILITY"
\&\fIlatexdiff-vc\fR uses external commands and is therefore
limited to Unix-like systems. It also requires the \s-1RCS\s0 version control
system and latex to be installed on the system.  Modules from Perl 5.8
or higher are required.
.SH "BUG REPORTING"
.IX Header "BUG REPORTING"
Please submit bug reports using the issue tracker of the github repository page \fIhttps://github.com/ftilmann/latexdiff.git\fR,
