6.1.2 Using Regular Expression Constants
----------------------------------------

Regular expression constants consist of text describing a regular
expression enclosed in slashes (such as '/the +answer/').  This minor
node describes how such constants work in POSIX 'awk' and 'gawk', and
then goes on to describe "strongly typed regexp constants", which are a
'gawk' extension.
