The bash man page refers to regex(3).  On my BSD (Mac OS X) system, that
refers to re_format(7), which documents the BRE and ERE regular expression
formats.  On an Ubuntu box, to choose a representative Linux example, that
refers to regex(7), which contains the same explanation, and the GNU regex
manual.  This sort of "chained" man page reference is common.

If you like info, `info regex' on a Linux box should display both pages.
