 Description:
 
 The regex compile function takes the source code of a regular expression,
-expressed as a Lisp data structure, and compiles it to a regular expression
-object.
+expressed as a Lisp data structure representing an abstract syntax tree, or
+else a regular expression specified as a character string, and compiles it to a
+regular expression object.
 
-Suitable source code is produced by regex-parse.
+If <form-or-string> is a character string, it is parsed to an
+abstract syntax tree first, if by a call to (regex-parse <form-or-string>). 
+If the parse is successful (the result is not nil) then
+it is compiled by a recursive call to regex-compile.
