A FileFinder plugin locates files within the distribution. This role exists so
that sets of files can be easily described in one configuration section and
then used by one or more other plugin.
Plugins implementing this role must provide a find_files method which will
be called with no arguments and must return an arrayref of files. (This
arrayref should not be re-used, as it may be altered once returned.)
For example, imagine a simple glob-like FileFinder that expects configuration
[Glob / RootModules]
glob = *.pm
This sets up a FileFinder named RootModules which will contain all pm
files in the root directory.
Another plugin that knows how to use FileFinder plugins might be configured
finder = RootModules
relocate_to = attic
Finders may operate on any rules they like, checking file size, content, name,
or other properties. They should re-perform their finding on each call to
find_files as the files in the distribution may have changed.
