| =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 can't handle a global input-only |
| :crlf so it has to be specified on each file open for text input. |
