+# This script modifies C code to use the hijacked NSPR routines that are
+# now baked into the JavaScript engine rather than using the NSPR
+# routines that they were based on, i.e. types like PRArenaPool are changed
+# to JSArenaPool.
+#
+# This script was used in 9/98 to facilitate the incorporation of some NSPR
+# code into the JS engine so as to minimize dependency on NSPR.
+#
+
+# Command-line: jsify.pl [options] [filename]*
+#
+# Options:
+#  -r         Reverse direction of transformation, i.e. JS ==> NSPR2
+#  -outdir    Directory in which to place output files
+
+
+# NSPR2 symbols that will be modified to JS symbols, e.g.
+# PRArena <==> JSArena
