/* This module contains a PCRE private debugging function for printing out the
internal form of a compiled regular expression, along with some supporting
local functions. This source file is used in two places:

(1) It is #included by pcre_compile.c when it is compiled in debugging mode
(PCRE_DEBUG defined in pcre_internal.h). It is not included in production
compiles. In this case PCRE_INCLUDED is defined.

(2) It is also compiled separately and linked with pcretest.c, which can be
asked to print out a compiled regex for debugging purposes. */

"inside information" compared to a program that strictly follows the PCRE API.
