-=head1 NAME
-
-h2ph - convert .h C header files to .ph Perl header files
-
-=head1 SYNOPSIS
-
-B<h2ph [-d destination directory] [-r | -a] [-l] [headerfiles]>
-
-=head1 DESCRIPTION
-
-I<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 B<-d> switch.
-
-If run with no arguments, filters standard input to standard output.
-
-=head1 OPTIONS
-
-=over 4
-
-=item -d destination_dir
-
-Put the resulting B<.ph> files beneath B<destination_dir>, instead of
-beneath the default Perl library location (C<$Config{'installsitearch'}>).
-
-=item -r
-
-Run recursively; if any of B<headerfiles> are directories, then run I<h2ph>
-on all files in those directories (and their subdirectories, etc.). B<-r>
-and B<-a> are mutually exclusive.
-
-=item -a
-
-Run automagically; convert B<headerfiles>, as well as any B<.h> files
-which they include. This option will search for B<.h> files in all
-directories which your C compiler ordinarily uses. B<-a> and B<-r> are
-mutually exclusive.
-
-=item -l
-
-Symbolic links will be replicated in the destination directory. If B<-l>
-is not specified, then links are skipped over.
-
-=item -h
-
-Put ``hints'' in the .ph files which will help in locating problems with
-I<h2ph>. In those cases when you B<require> a B<.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 B<.ph> files almost double in size when built using B<-h>.
-
-=item -D
-
-Include the code from the B<.h> file as a comment in the B<.ph> file.
-This is primarily used for debugging I<h2ph>.
-
-=item -Q
-
-``Quiet'' mode; don't print out the names of the files being converted.
-
-=back
-
-=head1 ENVIRONMENT
-
-No environment variables are used.
-
-=head1 FILES
-
- /usr/include/*.h
- /usr/include/sys/*.h
-
-etc.
-
-=head1 AUTHOR
-
-Larry Wall
-
-=head1 SEE ALSO
-
-perl(1)
-
-=head1 DIAGNOSTICS
-
-The usual warnings if it can't read or write the files involved.
-
-=head1 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.
