Unfortunately, the regex section of many manuals starts with a tutorial, and often leaves this question unanswered. If the answer for the package that brought you to this page is not below, please add it, in a direct and short format, with links if applicable.

1http://en.wikipedia.org/wiki/Comparison_of_regular_expression_engines has a table with fairly good coverage of popular tools (and some markedly less so). – tripleee Mar 25 '14 at 17:01

@tripleee: I added a column "Used by" to the Wikipedia page you mentioned, and it seems to have stuck (i.e., it has not been deleted by an editor). Would you be so kind as to add an answer summarizing your comments and pointers above and pointing to that table? Then I'll change the question if necessary, i.e., remove the "add below" clause, and mark your answer correct. Hopefully people will add the information to that table. – Leo Apr 11 '14 at 14:33
