Questions tagged [waf]

Waf is a Python-based framework for configuring, compiling and installing applications. It derives from the concepts of other build tools such as Scons, Autotools, CMake or Ant. If your question is about AWS WAF, use [amazon-waf] instead. If your question is about web application firewall, use [web-application-firewall] instead.

More information about the Waf project can be found at the following locations.

Help is also available:

  • on the waf-users mailing list
  • on IRC (#waf on freenode, with searchable, archived logs here).
