1 C.7 Summary
1 ===========
1 
1    * 'gawk''s extensions can be disabled with either the '--traditional'
1      option or with the '--posix' option.  The '--parsedebug' option is
1      available if 'gawk' is compiled with '-DDEBUG'.
1 
1    * The source code for 'gawk' is maintained in a publicly accessible
1      Git repository.  Anyone may check it out and view the source.
1 
1    * Contributions to 'gawk' are welcome.  Following the steps outlined
1      in this major node will make it easier to integrate your
1      contributions into the code base.  This applies both to new feature
1      contributions and to ports to additional operating systems.
1 
1    * 'gawk' has some limits--generally those that are imposed by the
1      machine architecture.
1 
1    * The extension API design was intended to solve a number of problems
1      with the previous extension mechanism, enable features needed by
1      the 'xgawk' project, and provide binary compatibility going
1      forward.
1 
1    * The previous extension mechanism is still supported in version 4.1
1      of 'gawk', but it _will_ be removed in the next major release.
