+This directory contains the source code of the pidl (Perl IDL)
+compiler.
+
+pidl.pl is the main file of pidl.
+
+Pidl works by building a parse tree from a .pidl file (a simple
+dump of it's internal parse tree) or a .idl file
+(a file format mostly like the IDL file format midl uses).
+The IDL file parser is in idl.yp (a yacc file converted to
+perl code by yapp)
+
+After a parse tree is present, pidl will call one of it's backends
+(which one depends on the options given on the command-line). Here is
+a list of current backends:
+
+client.pm - Generates client call functions in C
+dump.pm - Converts the parse tree back to an IDL file
+eparser.pm - Generates a parser for the ethereal network sniffer
+header.pm - Generates a header file with structures
+parser.pm - Generates pull/push functions for parsing
+server.pm - Generates server side implementation in C
+template.pm - Generates stubs in C for server implementation
+validator.pm - Validates the parse tree
+
+Other files in this directory are:
+tables.pl - Generates a table of available interfaces from a list of IDL files
+util.pm - Misc utility functions used by *.pm and pidl.pl
+
+Tips for hacking on pidl:
+ - Look at the pidl's parse tree by using the --keep option and looking
+ at the generated .pidl file.
+ - The various backends have a lot in common, if you don't understand how one
+ implements something, look at the others
+ - See pidl(1) and the documentation on midl
+ - See 'info bison' and yapp(1) for information on the file format of idl.yp
