+Unfortunately, Moose has a compile-time penalty. Though significant progress
+has been made over the years, the compile time penalty is a non-starter for
+some very specific applications. If you are writing a command-line application

+Moose. We recommend that you instead use L<HTTP::Engine> and FastCGI for the
+latter, if possible.
Mouse aims to alleviate this by providing a subset of Moose's functionality,
faster.
The idea is that, if you need the extra power, you should be able to run
C<s/Mouse/Moose/g> on your codebase and have nothing break. To that end,
we have written L<Any::Moose> which will act as Mouse unless Moose is loaded,
-in which case it will act as Moose.

+Moose, if you run into weird errors, it would be worth running:
+
+ ANY_MOOSE=Moose perl your-script.pl

+to see if the bug is caused by Mouse. Moose's diagnostics and validation are
+also much better.
