Revision 2.2 1997/01/06 22:57:52 guido
|

Jim's latest version.
|

|
||||
Revision 1.10 1997/01/02 15:19:55 chris
|
||||
checked in to be sure repository is up to date.
|
||||
|
||||
Revision 1.9 1996/12/27 21:40:29 jim
|
||||
Took out some lamosities in interface, like returning self from
|
||||
write.
|
||||
|
||||
Revision 1.8 1996/12/23 15:52:49 jim
|
||||
Added ifdef to check for CObject before using it.
|
||||
|
||||
Revision 1.7 1996/12/23 15:22:35 jim
|
||||
Finished implementation, adding full compatibility with StringIO, and
|
||||
then some.
|
||||
|
||||
We still need to take out some cStringIO oddities.
|
||||
|
||||
Revision 1.6 1996/10/15 18:42:07 jim
|
||||
Added lots of casts to make warnings go away.
