5# Wrapper for GNU groff to convert man pages to a few formats
6#
7# Usage: manconv.sh FORMAT [PAPER_SIZE] < in.1 > out.suffix
8#
9# FORMAT can be ascii, utf8, ps, or pdf. PAPER_SIZE can be anything that
10# groff accepts, e.g. a4 or letter. See groff_font(5). PAPER_SIZE defaults
11# to a4 and is used only when FORMAT is ps (PostScript) or pdf.
12#
13# Multiple man pages can be given at once e.g. to create a single PDF file
14# with continuous page numbering.
