NAME

       pl2pm - Rough tool to translate Perl4 .pl files to Perl5 .pm modules.

SYNOPSIS

       pl2pm files

DESCRIPTION

       pl2pm is a tool to aid in the conversion of Perl4-style .pl library files to Perl5-style library modules.  Usually, your old .pl file will
       still work fine and you should only use this tool if you plan to update your library to use some of the newer Perl 5 features, such as
       AutoLoading.

LIMITATIONS

       It's just a first step, but it's usually a good first step.

NAME

       h2ph - convert .h C header files to .ph Perl header files

SYNOPSIS

       h2ph [-d destination directory] [-r | -a] [-l] [headerfiles]

DESCRIPTION

       h2ph converts any C header files specified to the corresponding Perl header file format.  It is most easily run while in /usr/include:

	       cd /usr/include; h2ph * sys/*

       or

	       cd /usr/include; h2ph * sys/* arpa/* netinet/*

       or

	       cd /usr/include; h2ph -r -l .

       The output files are placed in the hierarchy rooted at Perl's architecture dependent library directory.	You can specify a different
       hierarchy with a -d switch.

       If run with no arguments, filters standard input to standard output.

OPTIONS

       -d destination_dir
	   Put the resulting .ph files beneath destination_dir, instead of beneath the default Perl library location ($Config{'installsitearch'}).

       -r  Run recursively; if any of headerfiles are directories, then run h2ph on all files in those directories (and their subdirectories,
	   etc.).  -r and -a are mutually exclusive.

       -a  Run automagically; convert headerfiles, as well as any .h files which they include.	This option will search for .h files in all
	   directories which your C compiler ordinarily uses.  -a and -r are mutually exclusive.

       -l  Symbolic links will be replicated in the destination directory.  If -l is not specified, then links are skipped over.

       -h  Put 'hints' in the .ph files which will help in locating problems with h2ph.  In those cases when you require a .ph file containing
	   syntax errors, instead of the cryptic

		   [ some error condition ] at (eval mmm) line nnn

	   you will see the slightly more helpful

		   [ some error condition ] at filename.ph line nnn

	   However, the .ph files almost double in size when built using -h.

       -D  Include the code from the .h file as a comment in the .ph file.  This is primarily used for debugging h2ph.

       -Q  'Quiet' mode; don't print out the names of the files being converted.

ENVIRONMENT

       No environment variables are used.

FILES

	/usr/include/*.h
	/usr/include/sys/*.h

       etc.

DIAGNOSTICS

       The usual warnings if it can't read or write the files involved.

BUGS

       Doesn't construct the %sizeof array for you.

       It doesn't handle all C constructs, but it does attempt to isolate definitions inside evals so that you can get at the definitions that it
       can translate.

       It's only intended as a rough tool.  You may need to dicker with the files produced.

       You have to run this program by hand; it's not run as part of the Perl installation.

       Doesn't handle complicated expressions built piecemeal, a la:

	   enum {
	       FIRST_VALUE,
	       SECOND_VALUE,
	   #ifdef ABC
	       THIRD_VALUE
	   #endif
	   };

       Doesn't necessarily locate all of your C compiler's internally-defined symbols.
