Introduction

Grace is a WYSIWYG 2D plotting tool for the X Window System and M*tif. Grace runs on practically any version of Unix-like OS. As well, it has been successfully ported to VMS, OS/2, and Win9*/NT/XP (some minor functionality may be missing, though).

Grace is a descendant of ACE/gr, also known as Xmgr.

Grace has two general-purpose mailing lists: grace and grace-announce. The first one, unmoderated, serves for general discussions of Grace. You can subscribe to it by sending an email to grace-request@plasma-gate.weizmann.ac.il with no subject line and the only word 'Subscribe' (without quotes, of course) in the body of the message.

The digest is sent once in a three days or when its size exceeds 32K.

The moderated grace-announce list is for new version or serious bug fix announcements only (which are automatically relayed to the first mailing list, too). The address to send subscription requests is grace-announce-request@plasma-gate.weizmann.ac.il.
