[rt-users] Replacing functions

[Ruslan Zakirov]

In the bottom of main .pm file you can find something like:
eval "require RT::EmailParser_Vendor";
die $@ if ($@ && $@ !~ qr{^Can't locate RT/EmailParser_Vendor.pm});
eval "require RT::EmailParser_Local";
die $@ if ($@ && $@ !~ qr{^Can't locate RT/EmailParser_Local.pm});

Such code loads matching _Vendor.pm and _Local.pm files. So you can
use local/lib/RT/EmailParser_Local.pm to override that function.
_Overlay.pm we use only where main .pm file is auto-generated by a
tool, but that doesn't mean you can not use _Local.pm files for those
without overlay.pm.

You can use the following command to test that:
find lib/ -type f -name '*.pm' | xargs grep -lP 'require\s.*_Local'

Please, update the wiki with this info so next time people will get
everything right without asking.
