latexdiff\-vc \- wrapper script that calls latexdiff for different versions of a file under version management (CVS, RCS or SVN)

.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\s0, \s-1RCS\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\s0, \s-1CVS\s0, \s-1SVN\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.
