Just a note to say how much fun it was for me to try the Test::Compile::Internal module, which zips through every Perl module and script in my cgi-bin directory and its subdirectories, making sure each such file successfully compiles.

This lets me feel more at ease about there not being any lurking problems that have arisen due to my having renamed or deleted some custom module, and that scripts or modules I'm still developing haven't "use"d a module and its specified subroutines (whether custom or in my Perl libraries) in a way that misspelled the module name or the subroutine name, or that tries to import a subroutine that doesn't actually exist in the "use"d module (such as a subroutine I meant to add to a "use"d custom module but never got around to adding).

#!/opt/perl524

use strict;
use warnings;

use Test::Compile::Internal;

my $test = Test::Compile::Internal->new();

$test->all_files_ok( '/www/cgi-bin' );

$test->done_testing();
