=head2 Cache directory

By default the cache file is written to the directory
F<~/.tkpod_cache> (Unix systems), or the data directory as determined
by L<File::HomeDir> (Windows, MacOSX). If everything fails, then the
temporary directory (F</tmp> or the OS equivalent) is used.

If necessary, then the last path component will be created (that is,
F<.tkpod_cache> will be created if the directory does not exist).

To use another cache directory set the environment variable
L</TKPODCACHE>.

=head1 ENVIRONMENT

=over

=item TKPODCACHE

Use a custom cache file instead of a file in the L<cache directory|/Cache directory>.
The following placeholders are recognized:

=over

=item %v

The perl version.

=item %o

The OS (technically correct: the archname, which can include tokens
like "64int" or "thread").

=item %u

The user id.

=back

Example for using F</some/other/directory> for the cache file location:

	TKPODCACHE=/some/other/directory/pods_%v_%o_%u; export TKPODCACHE

or

	setenv TKPODCACHE /some/other/directory/pods_%v_%o_%u

depending on your shell (sh-like or csh-like).
