+   Revision 1.3.2.1  2000/07/12 22:20:55  sjboddie
+   merged changes to trunk into New_Config_Format branch
+
+   Revision 1.5  2000/05/19 04:56:01  sjboddie
+   added gsdl_system function for spawning off new processes under windows
+
+   Revision 1.4  2000/05/04 05:16:23  sjboddie
+   Moved dm_safe from htmlutils to gsdltools. Also made it escape '\'
+   characters to prevent their mysterious disapearance from things like
+   windows filenames when they get passed through the macro expander.
