+ * This is a grab-bag of non-domain-specific expansions

+ * Documentation is generated from the comments at the head of each function.
+ * The comment should have a '$' and the expansion name on the first line and
+ * should have a blank line between each paragraph.

+ * To make a bulleted list, put a '-' at the start of each line.
+ *
+ * You can currently get away with troff markup but this is horribly ugly and
+ * might be changed.
