The File::Basename module provides functions to parse pathnames
into their individual components. The dirname function pulls
out the directory portion and basename the nondirectory portion.
The more elaborate fileparse function picks out the full pathname
into the directory name, the filename, and the suffix; you must
supply a list of regular expressions describing the suffixes that
interest you. The examples above illustrate how choice of suffix
patterns affects the result. By default, these functions parse
pathnames according to the native conventions of your current
platform. The fileparse_set_fstype function selects a different
platform's parsing rules, such as fileparse_set_fstype("VMS")
to parse names using VMS rules, even when running on non-VMS systems.
