This script generates the manpage.
|
|
|
|
Example: managen <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.
