=head1 NAME
Tk::Xrm - X Resource/Defaults/Options routines that obey the rules.
=for pm Tk/Xrm.pm
=for category Creating and Configuring Widgets
=head1 SYNOPSIS
use Tk;
use Tk::Xrm;
=head1 DESCRIPTION
Using this modules causes Tk's Option code to be replaced by versions
which use routines from <X11/Xresource.h> - i.e. same ones every other
X toolkit uses.
Result is that "matching" of name/Class with the options database follows
the same rules as other X toolkits. This makes it more predictable,
and makes it easier to have a single ~/.Xdefaults file which gives sensible
results for both Tk and (say) Motif applications.
=head1 BUGS
Currently B<optionAdd>(I<key> =E<gt> I<value>?, I<priority>?) ignores optional
priority completely and just does XrmPutStringResource().
Perhaps it should be more subtle and do XrmMergeDatabases() or
XrmCombineDatabase().
This version is a little slower than Tk's re-invention but there is
more optimization that can be done.
