=head1 DESCRIPTION
This module provides a quick, convenient way of bootstrapping a user-local Perl
Rather basic shell detection. Right now anything with csh in its name is
assumed to be a C shell or something compatible, and everything else is assumed
-to be Bourne. If the C<SHELL> environment variable is not set, a
-Bourne-compatible shell is assumed.
+to be Bourne, except on Win32 systems. If the C<SHELL> environment variable is
+not set, a Bourne-compatible shell is assumed.
Bootstrap is a hack and will use CPAN.pm for ExtUtils::MakeMaker even if you
have CPANPLUS installed.
Patches very much welcome for any of the above.
+On Win32 systems, does not have a way to write the created environment variables
+to the registry, so that they can persist through a reboot.
+
+=head1 TROUBLESHOOTING
+
+If you've configured local::lib to install CPAN modules somewhere in to your
+home directory, and at some point later you try to install a module with C<cpan
+-i Foo::Bar>, but it fails with an error like: C<Warning: You do not have
+permissions to install into /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux at
+/usr/lib64/perl5/5.8.8/Foo/Bar.pm> and buried within the install log is an
+error saying C<'INSTALL_BASE' is not a known MakeMaker parameter name>, then
+you've somehow lost your updated ExtUtils::MakeMaker module.
+
+To remedy this situation, rerun the bootstrapping procedure documented above.
+
+Then, run C<rm -r ~/.cpan/build/Foo-Bar*>
+
+Finally, re-run C<cpan -i Foo::Bar> and it should install without problems.
+
=head1 ENVIRONMENT
=over 4
=item SHELL
+=item COMSPEC
+
local::lib looks at the user's C<SHELL> environment variable when printing out
commands to add to the shell configuration file.
+On Win32 systems, C<COMSPEC> is also examined.
