30 | Revision 1.5 2000/05/19 04:56:01 sjboddie
|
---|
31 | added gsdl_system function for spawning off new processes under windows
|
---|
32 |
|
---|
33 | Revision 1.4 2000/05/04 05:16:23 sjboddie
|
---|
34 | Moved dm_safe from htmlutils to gsdltools. Also made it escape '\'
|
---|
35 | characters to prevent their mysterious disapearance from things like
|
---|
36 | windows filenames when they get passed through the macro expander.
|
---|
37 |
|
---|
38 | Revision 1.3 2000/04/06 19:58:01 cs025
|
---|
39 | Correcting a correction - reinstated all lib files due to silly
|
---|
40 | CVS confusion.

---|
41 |

42 | Revision 1.1 2000/02/29 01:37:00 sjboddie
