[Module::Build] [PATCH] Write minimal META.yml unless -e YAML.pm

[Randy W. S. <Ra...@Th...>]

I'm not sure this patch is clean or complete (I'm up past my bedtime), 
but I thought I'd post for comments. This patch:

  - Adapts the 'author' parameter to accept either a string or anonymous 
array of strings for multiple authors.

  - Initialize dist_author and dist_abstract like dist_(name|version).

  - Adds authored_by field to F<META.yml> and adapts PPMMaker.pm to 
write multiple AUTHOR tags if appropriate in PPD files (which is allowed 
by the PPD spec).

  - Adds abstract field to the F<META.yml> file.

  - If YAML.pm is not installed, print a warning and generate a minimal 
META.yml file.


Regards,
Randy.
