That link points to the RewriteEngine version.
I use:
   ScriptAlias /myapp /path/to/myapp/bin/dispatch.fcgi

Note:
- dispatch.fcgi is NOT in the document root
- Do NOT detach
-- in dispatch.fcgi
-- my $server = Plack::Handler::FCGI->new(nproc => 1, detach => 0);
- Running the same code as stand-alone for testing needs some tweeks

I have a scriptalias in my config.yml scriptalias: "/myapp"
and a plugin that exports the DSL keyword scriptalias
Loading sub-apps like this:

if (setting('environment') eq 'production') {
     load_app 'Subapp', prefix => '/subapp';
} else {
     load_app 'Subapp', prefix => scriptalias . '/subapp';
}

Mmm, maybe overkill...
setting some $scriptalias can construct a prefix "$scriptalias/subapp"

Running 'perl bin/app.pl' just works.

One can use this to slowly convert

   /cgi-bin/subapp1.pl
   /cgi-bin/subapp2.pl

to

   /myapp/subapp1
   /myapp/subapp2
