2001-12-12 Matthias Klose <doko@debian.org>

generation of more than one man page from one source.
Add '-' to set of valid chars for an identifier.
Let -D option accept flags of the form <flag>=<value>.
Use \s+ for whitespace detection in '@c man' lines.
Handle @set and @clear independent of $output.
Substitute all @value{}'s in a line.

in verbatim blocks specially. Handle @unnumbered, @unnumberedsec
and @center. Allow [a-z] after @enumerate. Handle 0 and numbers
greater than 9 in enumerations.
