| [1176] | 30 | Revision 1.5 2000/05/19 04:56:01 sjboddie
|
|---|
| 31 | added gsdl_system function for spawning off new processes under windows
|
|---|
| 32 |
|
|---|
| [1146] | 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 |
|
|---|
| [1076] | 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 |
