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