28 %(argv0)s: XML to nroff converter
29 Converts the XML format supplied as input into an nroff-formatted manpage.
30 usage: %(argv0)s [OPTIONS] INPUT.XML [VAR=VALUE]...
31 where INPUT.XML is a manpage in an OVS-specific XML format.
33 Each VAR, when enclosed by "@"s in the input, is replaced by its
34 corresponding VALUE, with characters &<>"' in VALUE escaped.
36 The following options are also available:
37 --version=VERSION use VERSION to display on document footer
38 -h, --help display this help message\
