/*
|
||
* For Emacs in SunView/Sun-Windows: (supported by Sun Unix v3.2 or greater)
|
||
* Insert a notifier filter-function to convert all useful input
|
||
* to "key" sequences that emacs can understand. See: Emacstool(1).
|
||
*
|
||
* Author: Jeff Peck, Sun Microsystems, Inc. <peck@eng.sun.com>
|
||
*
|
||
* Original Idea: Ian Batten
|
||
* Updated 15-Mar-88, Jeff Peck: set IN_EMACSTOOL, TERM, TERMCAP
|
||
* Updated 10-Sep-88, Jeff Peck: add XVIEW and JLE support
|
||
* Updated 8-Oct-90, Jeff Peck: add Meta-bit for Xview
|
||
* Updated 6-Mar-91, Jeff Peck: Hack to detect -Wt invocation
|
||
* [note, TTYSW limitation means you must Click-To-Type in Openwin]
|
||
* [fixed in OW3 or use local/tty.o]
|
||
* for better results, this should move to using TERMSW.
|
||
* Updated 10-Mar-91, Jeff Peck, et al: support for TERMSW (TTERM)
|
||
* allows point-to-type even in OW2
|
||
*
|
||
* [note: xvetool should be started with the "-nw" flag for emacs!]
