+=head1 NAME
+
+ltximg - LaTeX environments to image and standalone files
+
+=head1 SYNOPSIS
+
+B<ltximg> [E<lt>I<options>E<gt>] [S<-->] E<lt>I<filename>E<gt>.E<lt>I<tex>|I<ltx>E<gt>
+
+=head1 DESCRIPTION
+
+B<ltximg> automates the process of extracting and converting
+environments from LaTeX file to image formats and I<standalone> files
+using I<ghostscript> and I<poppler-utils>. Generates a one file with
+only extracted environments and other with all extracted environments
+converted to C<\includegraphics>.
+
+By default the extracted environments are:
+
+B<preview> B<pspicture> B<tikzpicture> B<pgfpicture> B<psgraph> B<postscript> B<PSTexample>
+
+=head1 OPTIONS
+
+Options that accept a value require either a blank space or C<=> between
+the option and the value. Multiple short options can be bundling and
+if the last option takes a comma separated list you need C<--> at the end.
+Relative or absolute paths for directories and files is not supported.
+
+If used without [E<lt>I<options>E<gt>] the extracted environments are converted
+to I<pdf> image format and saved in C<./images> directory using C<pdflatex>
+and I<preview> package for process.
+
