+.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 (git, subversion (\s-1SVN\s0), mercurial (hg), \s-1CVS, RCS\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, \fB\-\-git\fR or \fB\-\-hg\fR" 4
+.IX Item "--rcs, --svn, --cvs, --git or --hg"
+Set the version control system used. 
+If no version system is specified, latexdiff-vc will venture a guess.
+.Sp
+latexdiff-cvs, latexdiff-rcs etc are variants of latexdiff-vc which default to 
+the respective versioning system. However, this default can still be overridden using the options above.
+.Sp
+Note that hg needs to support the \f(CW\*(C`\-\-root\*(C'\fR option (version >= 2.9)
+.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, GIT\s0 or \s-1HG\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

+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\-\-flatten,\-\-flatten=keep\-intermediate\fR" 4
+.IX Item "--flatten,--flatten=keep-intermediate"
+If combined with \f(CW\*(C`\-\-git\*(C'\fR, \f(CW\*(C`\-\-svn\*(C'\fR or \f(CW\*(C`\-\-hg\*(C'\fR option or the corresponding modes, check out the revisions to compare in a separate temporary directory, and then pass on option \f(CW\*(C`\-\-flatten\*(C'\fR to latexdiff. The directory in which \f(CW\*(C`latexdiff\-vc\*(C'\fR is invoked defines the subtree which will be checked out.
+Note that if additional files are needed which are not included in the flatten procedure (package files, included graphics), they need to be accessible in the current directory. If you use bibtex, it is recommended to include the \f(CW\*(C`.bbl\*(C'\fR file in the version management.
+.Sp
+The generic usage of this function is : \f(CW\*(C`latexdiff\-vc \-\-flatten \-r rev1 [\-r rev2] master.tex\*(C'\fR where master.tex is the project file containing the highest level of includes etc.
+.Sp
+With \f(CW\*(C`\-\-flatten=keep\-intermediate\*(C'\fR, the intermediate revision snapshots are kept in the current directory (Default is to store them in a temporary directory and delete them after generating the diff file.)
+.IP "\fB\-\-config var1=val1,var2=val2,...\fR or \fB\-c var1=val1,..\fR" 4
+.IX Item "--config var1=val1,var2=val2,... or -c var1=val1,.."
+.PD 0
+.IP "\fB\-\-only\-changes\fR" 4
+.IX Item "--only-changes"
+.PD
+Post-process the output such that only pages with changes on them are displayed. This requires the use of subtype \s-1ZLABEL \s0
+in latexdiff, which will be set automatically, but any manually set \-s option will be overruled (also requires zref package to 
+be installed). (note that this option must be combined with \-\-ps or \-\-pdf to make sense)
+.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\-\-run\fR" 4
+.IX Item "--run"
+run latex command on diff file after generation of diff file.
+.IP "\fB\-\-dvi\fR" 4
+.IX Item "--dvi"
+run latex and dvixxx commands after generation of diff file.
+.IP "\fB\-c configfile\fR" 4
+.IX Item "-c configfile"
+Set configuration variables for latexdiff and latexdiff-vc.  The option can be repeated to set different
+variables (as an alternative to the comma-separated list).
+Available variables for latexdiff-vc:

+.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.
+Note that this is not just a shortcut for setting configuration variable but also triggers 
+some special behaviour.
+.IP "\fB\-\-show\-config\fR" 4
+.IX Item "--show-config"
+Show values of configuration variables.
