=begin comment
This script generates the manpage.
Example: gen.pl <command> [files] > curl.1
Dev notes:
We open *input* files in :crlf translation (a no-op on many platforms) in
case we have CRLF line endings in Windows but a perl that defaults to LF.
Unfortunately it seems some perls like msysgit cannot handle a global input-only
:crlf so it has to be specified on each file open for text input.
