# wiki2ms
# convert from wikifs(6) format to ms format
# usage:
#	wiki2ms document.wiki https://cloud9p.org/man # normal wiki text
#	wiki2ms document.wms https://cloud9p.org/man # wiki with ms macros
# bugs:
# man page linking is better to be optional
# very wasteful
# ms output could've been better
# some of wikifs functionality is not yet implmented:
# proper parsing for links
