+'''Template:Category handler''' is intended as a metatemplate that helps templates categorize pages. It also suppresses categories depending on the namespace or subpage.
+== Usage ==
+Categories are entered as unnamed parameters, as shown.
+<pre>{{Category handler | cat 1 | cat 2 | cat 3 }}</pre>
+For example, the code below
+: <code><nowiki>{{Category handler | Abstract MOS patterns | 8-tone scales}}</nowiki></code>
+categorizes the page under the following categories.
+: <code><nowiki>[[Category:Abstract MOS patterns]][[Category:8-tone scales]]</nowiki></code>
+For testing purposes, categories can be turned off by adding <code><nowiki>debug=1</nowiki></code>. Modifying the previous example
+: <code><nowiki>{{Category handler | Abstract MOS patterns | 8-tone scales | debug=1 }}</nowiki></code>
+disables categories. Typical use as part of another template should instead use something like <code><nowiki>debug={{{debug|}}}</nowiki></code>, so that <code><nowiki>debug=1</nowiki></code> can be added to an instance of that template.
