This also eliminates the need for f_restricted on frames. This in turn negates the need for PyEval_GetRestricted() and PyFrame_IsRestricted(). ........ r55303 | brett.cannon | 2007-05-13 19:22:22 -0700 (Sun, 13 May 2007) | 2 lines Remove the md5 and sha modules. ........ r55305 | george.yoshida | 2007-05-13 19:45:55 -0700 (Sun, 13 May 2007) | 2 lines fix markup ........ r55306 | neal.norwitz | 2007-05-13 19:47:57 -0700 (Sun, 13 May 2007) | 1 line Get the doc building again after some removals. ........ r55307 | neal.norwitz | 2007-05-13 19:50:45 -0700 (Sun, 13 May 2007) | 1 line Get test_pyclbr passing again after getstatus was removed from commands. This "test case" was weird since it was just importing a seemingly random module. Remove the import ........ r55322 | brett.cannon | 2007-05-14 14:09:20 -0700 (Mon, 14 May 2007) | 3 lines Remove the compiler package. Will eventually need a mechanism to byte compile an AST. ........
