Revision:	1.6
Committed:	2001-01-04T19:50:23Z (23 years, 11 months ago) by cebix
Branch:	MAIN
Changes since 1.5:	+4 -4 lines
Log Message:	- removed the INT16 prefs item type; use INT32 instead - AmigaOS/Unix: it's now possible to specify preferences items on the command line - Unix: command line options now take "--"-prefix, e.g. "--rominfo"
