When writing code that should run on several platforms you have various things to consider. One of them is finding the home directory of the current user. Doing that on an arbitrary OS used to be difficult or at least error prone but thanks to Adam Kennedy and his File::HomeDir module it is just calling the my_home method now.

For the location of the configuration files one should use the my_data method

What is not yet clear to me is how should I call the application specific configuration files (or if I use a full directory, the configuration directory)?
.something is the Unix/Linux style.
What should be on windows?
And for other OS-es?
Is there a standard platform independent way to generate names of the configuration files?

Update

I slightly updated the text above but also interesting the trouble Subversion has with the .svn directories.
I couldn't yet figure out the convention used in vi (on Windows) either.
