 Warning: these functions are not thread-safe.
 
+\strong{Obsolescence note:}
+This module is obsolete as of Python version 1.5; it is still being
+maintained because much existing code still uses it.  All new code in
+need of regular expressions should use the new \code{re} module, which
+supports the more powerful and regular Perl-style regular expressions.
+Existing code should be converted.  The standard library module
+\code{reconvert} helps in converting \code{regex} style regular
+expressions to \code{re} style regular expressions.  (For more
+conversion help, see the URL
+\file{http://starship.skyport.net/crew/amk/regex/regex-to-re.html}.)

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
