+# MKlib_gen.sh -- generate sources from curses.h macro definitions
+#
+# ($Id: MKlib_gen.sh,v 1.11 1998/01/17 14:16:52 Juan.Jose.Garcia.Ripoll Exp $)
+#
+# The XSI Curses standard requires all curses entry points to exist as
+# functions, even though many definitions would normally be shadowed
+# by macros.  Rather than hand-hack all that code, we actually
+# generate functions from the macros.
+#
+# This script accepts a file of prototypes on standard input.  It discards
+# any that don't have a `generated' comment attached. It then parses each
+# prototype (relying on the fact that none of the macros take function 
+# pointer or array arguments) and generates C source from it.
+#
+# Here is what the pipeline stages are doing:
+#
+# 1. sed: extract prototypes of generated functions
+# 2. sed: decorate prototypes with generated arguments a1. a2,...z
+# 3. awk: generate the calls with args matching the formals 
+# 4. sed: prefix function names in prototypes so the preprocessor won't expand
+#         them.
+# 5. cpp: macro-expand the file so the macro calls turn into C calls
+# 6. awk: strip the expansion junk off the front and add the new header
+# 7. sed: squeeze spaces, strip off gen_ prefix, create needed #undef
+#

+/*
+ * This module is intended to encapsulate ncurses's interface to pointing
+ * devices.
+ *
+ * The first method used is xterm's internal mouse-tracking facility.
+ * The second is Alessandro Rubini's GPM server.
+ *
+ * Notes for implementors of new mouse-interface methods:
+ *
+ * The code is logically split into a lower level that accepts event reports
+ * in a device-dependent format and an upper level that parses mouse gestures
+ * and filters events.  The mediating data structure is a circular queue of
+ * MEVENT structures.
+ *
+ * Functionally, the lower level's job is to pick up primitive events and
+ * put them on the circular queue.  This can happen in one of two ways:
+ * either (a) _nc_mouse_event() detects a series of incoming mouse reports
+ * and queues them, or (b) code in lib_getch.c detects the kmous prefix in
+ * the keyboard input stream and calls _nc_mouse_inline to queue up a series
+ * of adjacent mouse reports.
+ *
+ * In either case, _nc_mouse_parse() should be called after the series is
+ * accepted to parse the digested mouse reports (low-level MEVENTs) into
+ * a gesture (a high-level or composite MEVENT).
+ *
+ * Don't be too shy about adding new event types or modifiers, if you can find
+ * room for them in the 32-bit mask.  The API is written so that users get
+ * feedback on which theoretical event types they won't see when they call
+ * mousemask. There's one bit per button (the RESERVED_EVENT bit) not being
+ * used yet, and a couple of bits open at the high end.
