sub get_package_symbol {
=item B<meta>
-=item B<initialize>
+=item B<initialize ($package_name)>
=item B<name>
+This is a read-only attribute which returns the package name for the
+given instance.
+
=item B<namespace>
-=item B<add_package_symbol>
+This returns a HASH reference to the symbol table. The keys of the
+HASH are the symbol names, and the values are typeglob references.
+
+=item B<add_package_symbol ($variable_name, ?$initial_value)>
+
+Given a C<$variable_name>, which must contain a leading sigil, this
+method will create that variable within the package which houses the
+class. It also takes an optional C<$initial_value>, which must be a
+reference of the same type as the sigil of the C<$variable_name>
+implies.
+
+=item B<get_package_symbol ($variable_name)>
-=item B<get_package_symbol>
+This will return a reference to the package variable in
+C<$variable_name>.
-=item B<has_package_symbol>
+=item B<has_package_symbol ($variable_name)>
-=item B<remove_package_symbol>
+Returns true (C<1>) if there is a package variable defined for
+C<$variable_name>, and false (C<0>) otherwise.
-=item B<remove_package_glob>
+=item B<remove_package_symbol ($variable_name)>
+
+This will attempt to remove the package variable at C<$variable_name>.
+
+=item B<remove_package_glob ($glob_name)>
+
+This will attempt to remove the entire typeglob associated with
+C<$glob_name> from the package.
=item B<list_all_package_symbols>
+This will list all the glob names associated with the current package.
+By inspecting the globs returned you can discern all the variables in
+the package.
