+Perf-Trace-Util version 0.01
+============================
+
+This module contains utility functions for use with perf script.
+
+Core.pm and Util.pm are pure Perl modules; Core.pm contains routines
+that the core perf support for Perl calls on and should always be
+'used', while Util.pm contains useful but optional utility functions
+that scripts may want to use. Context.pm contains the Perl->C
+interface that allows scripts to access data in the embedding perf
+executable; scripts wishing to do that should 'use Context.pm'.
+
+The Perl->C perf interface is completely driven by Context.xs. If you
+want to add new Perl functions that end up accessing C data in the
+perf executable, you add desciptions of the new functions here.
+scripting_context is a pointer to the perf data in the perf executable
+that you want to access - it's passed as the second parameter,
+$context, to all handler functions.
+
+After you do that:
+
+ perl Makefile.PL # to create a Makefile for the next step
+ make # to create Context.c
+
+ edit Context.c to add const to the char* file = __FILE__ line in
+ XS(boot_Perf__Trace__Context) to silence a warning/error.
+
+ You can delete the Makefile, object files and anything else that was
+ generated e.g. blib and shared library, etc, except for of course
+ Context.c
+
+ You should then be able to run the normal perf make as usual.
+
+INSTALLATION
+
+Building perf with perf script Perl scripting should install this
+module in the right place.
+
+You should make sure libperl and ExtUtils/Embed.pm are installed first
+e.g. apt-get install libperl-dev or yum install perl-ExtUtils-Embed.
