Hi Mark, I just released Cog.pm to CPAN ( as http://search.cpan.org/~ingy/Cog-0.03/<http://search.cpan.org/%7Eingy/Cog-0.03/>), and became aware that the module name 'Cog' is indexed by CPAN to your module distribution CNC-Cog.
I took a close look at CNC-Cog. It installs a module called CNC::Cog, and does not install a module called Cog.pm. However, since you packaged the module as ./Cog.pm instead of lib/CNC/Cog.pm, and since you also have the line 'package Cog;' in the module, your module got indexed as Cog (as well as CNC::Cog). Most likely this was not your intention. This means that when people install 'CNC::Cog' (using the cpan installation tools) they get your module, but when they install 'Cog' they also get CNC::Cog, instead of my module 'Cog.pm', which is what they would expect. I am writing this email to ask your permission for CPAN to index your module as 'CNC::Cog' and index mine as 'Cog'. Is that OK with you? Cheers, Ingy
