    # Below, we strip out all but preprocessor directives.
    # We have to take care of situations like
    #       #if defined(FOO) BAR   /* comment line 1
    #                                 more comment lines */
    # If we just delete text starting from the '/*' to the end of line, we will
    # screw up cases like
    #      #if defined(FOO)    /* comment */ \
    #          && defined(BAR) /* comment */ \
    #          && defined(BAZ) /* comment */ \
    #               etc.
    # Also, in lines like
    #      #defined FOO(a,b)    a/**/b
    # the comment may be important and so needs to be retained.
    # This code processes the single-line comments first; it assumes there is
    # at most one straightforward comment per continued preprocessor line,
    # replacing each non-empty comment (and its surrounding white space) by a
    # single space.  (sed only has a greedy '*' quantifier, so this doesn't
    # work right if there are multiple comments per line, and strings can look
    # like comments to it; both are unlikely in a preprocessor statement.) Any
    # continuation line is joined, and the process repeated on the enlarged
    # line as long as there are continuations.  At the end, if there are any
    # comments remaining, they are either completely empty or are like the
    # first situation.  The latter are just deleted by first deleting to the
    # end of line (including preceding white space) things that start with '/*'
    # and the next char isn't a '*'; then things that start with '/**', but the
    # next char isn't a '/'.  (Subsequent lines of the comment are irrelevant
    # and get dropped.)  At the end, we unjoin very long lines to avoid
    # preprocessor limitations

=head1 NAME

Devel::PatchPerl - Patch perl source a la Devel::PPPort's buildperl.pl

=head1 VERSION

version 1.52

=head1 SYNOPSIS

  use strict;
  use warnings;

  use Devel::PatchPerl;

  Devel::PatchPerl->patch_source( '5.6.1', '/path/to/untarred/perl/source/perl-5.6.1' );

=head1 DESCRIPTION

Devel::PatchPerl is a modularisation of the patching code contained in L<Devel::PPPort>'s
C<buildperl.pl>.

It does not build perls, it merely provides an interface to the source patching
functionality.

=head1 FUNCTION

=over

=item C<patch_source>

Takes two parameters, a C<perl> version and the path to unwrapped perl source for that version.
It dies on any errors.

If you don't supply a C<perl> version, it will attempt to auto-determine the
C<perl> version from the specified path.

If you don't supply the path to unwrapped perl source, it will assume the
current working directory.

=item C<determine_version>

Takes one optional parameter, the path to unwrapped perl source. It returns the perl version
of the source code at the given location. It returns undef on error.

If you don't supply the path to unwrapped perl source, it will assume the
current working directory.

=back

=head1 PLUGIN SYSTEM

See L<Devel::PatchPerl::Plugin> for details of Devel::PatchPerl's plugin system.

=head1 CAVEAT

Devel::PatchPerl is intended only to facilitate the C<building> of perls, not to
facilitate the C<testing> of perls. This means that it will not patch failing tests
in the perl testsuite.
