# Identical to +find+ except +select+ returns the matching files as an _array_. (+find+ returns nil, which is not very useful if you actually wanted an array.)

# Calls the associated block with the name of every file and directory listed as arguments, then recursively on their subdirectories, and so on.
#
# Return a true (non-false) value from the block for every path that you want to be returned in the resulting array.
#
# You can still use <tt>Find.prune</tt>.
