# NAME
# 	markhpage - convert Markdown file to HTML page
# SYNOPSIS
# 	markhpage [-c cssuri] [-t title] [ file ]
# DESCRIPTION
# 	The rc script markhpage uses markdown(1) to interpret
# 	text in file (or standard input) and inserts its HTML
#	representation into the body element of a complete
#	HTML document on the standard output. Under -c, the
#	path or URL cssuri is inserted as a stylesheet <link> in
# 	the output <head>. The (possibly quoted) title argument to -t
#	gives a <title> for the output.
