-/*
- * 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. <address@hidden>
- *
- * 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!]
