=head1 NAME

Pod::Tree::PerlDist - translate Perl distribution documentation to HTML

=head1 SYNOPSIS

  $perl_map  = new Pod::Tree::PerlMap;
  $perl_dist = new Pod::Tree::PerlDist $perl_dir, $HTML_dir, $perl_map, %opts;

  $perl_dist->scan;
  $perl_dist->index;
  $perl_dist->translate;

  $top = $perl_dist->get_top_entry;

=head1 DESCRIPTION

C<Pod::Tree::PerlDist> translates documents in the Perl
distribution to HTML. These include F<Changes>, F<README>, and
assored other files that appear in the top level of the Perl 
source tree.

Files that contain PODs are parsed as PODs;
files that do not contain PODs are converted to HTML
as preformatted text.

C<Pod::Tree::PerlDist> generates and uses an index of the files 
that it finds to construct HTML links.
Other modules can also use this index.

=head1 METHODS

=over 4

=item I<$perl_dist> = C<new> C<Pod::Tree::PerlDist> I<$perl_dir>,
I<$HTML_dir>, I<$perl_map>, I<%options>

Creates and returns a new C<Pod::Tree::PerlDist> object.

I<$perl_dir> is the root of the Perl source tree.

I<$HTML_dir> is the directory where HTML files will be written.

I<$perl_map> maps file names to URLs.

I<%options> are passed through to C<Pod::Tree::HTML>.

=item I<$perl_dist>->C<scan>

Scans the top level of the Perl source tree for documentation files.
Files that do not generally contain user-level documentation,
such as source files, are ignored.
The search does not recurse through subdirectories.

Each file that is located is entered into I<$perl_map>.

=item I<$perl_dist>->C<index>

Generates a top-level index of all the distribution documents, 
and writes it to I<HTML_dir>C</dist.html>.

=item I<$perl_dist>->C<translate>

Translates each distribution document found by C<scan> to HTML.
The HTML pages are written to I<HTML_dir>.

=item I<$perl_dist>->C<get_top_entry>

Returns a hash reference of the form

  { URL         => $URL,
    description => $description }

C<Pod::Tree::PerlTop> uses this to build a top-level index of all the 
Perl PODs.
