svn+ssh://pythondev@svn.python.org/python/branches/p3yk ........ r55271 | fred.drake | 2007-05-11 10:14:47 -0700 (Fri, 11 May 2007) | 3 lines remove jpeg, panel libraries for SGI; there is more IRIX stuff left over, I guess that should be removed too, but will leave for someone who is sure ........ r55280 | fred.drake | 2007-05-11 19:11:37 -0700 (Fri, 11 May 2007) | 1 line remove mention of file that has been removed ........ r55301 | brett.cannon | 2007-05-13 17:38:05 -0700 (Sun, 13 May 2007) | 4 lines Remove rexec and Bastion from the stdlib. 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. ........
