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

remove mention of file that has been removed

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.

fix markup

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.
