=head1 Random Notes on Irssi Internals.


=head2 Display Output

Irssi has to deal with a whole bunch of things between a script print() and actually
putting it on the screen.

Some of these things are:

=over 4

=item Message Levels

=item Abstract Replacements

=item Theme formats

=item Module  (C</format>) formats

=back

==head3 Message Levels

Message levels are defined in F<src/core/levels.h> and some
support functions in F<src/core/levels.c>

We have:

=over 4

=item C<int level_get(str level)>

Special cases: C<ALL, *> both return MSGLEVEL_ALL, and C<NEVER> returns 0.
The remainder are looked up in a big static string array by name to
find the appropriate numeric level.  Partial matches are permitted as
long as they are unambigious.


=item C<int level2bits(str level, int *errorp)>

=item C<str bits2level(int bits)>

=item C<int combine_level(int dest, str src)>
