+NSPR 2.0 libc functions
+-----------------------
+
+Last edited: AOF 04 March 1997
+
+This directory contains various libc-types of functions. All functions in
+this directory are platform independent, thread friendly (both safe and
+efficient). They are contributed from various sources, though the contri-
+butions are monitored by the NSPR group (mailto:freier).
+
+All API items exported by these functions will contain the same three
+character prefix, "PL_" (Portable Library). Internal function names
+that are not exported (static) are of little concern, though some caution
+must be used on those elements that are 'extern' but not really intended
+to be part of the API. Those should all have a prefix of "_PL_" (is that
+legal?).
+
+The responsibility for contributions in this area are distributed among
+all interested parties.
+
