NAME

       Algorithm::Dependency::Source::File - File source for dependency heirachys

DESCRIPTION

       Algorithm::Dependency::Source::File implements a source where the items are stored in a
       flat file or a relatively simple format.

   File Format
       The file should be an ordinary text file, consisting of a series of lines, with each line
       completely containing the information for a single item.  Blank lines, or lines beginning
       with the hash character '#' will be ignored as comments.

       For a single item line, only word characters will be used. A 'word character' consists of
       all letters and numbers, and the underscore '_' character.  Anything that is not a word
       character will be assumed to be a seperator.

       The first word will be used as the name or id of the item, and any further words in the
       line will be used as other items that this one depends on. For example, all of the
       following are legal.

         # A single item with no dependencies
         Foo

         # Another item that depends on the first one
         Bar Foo

         # Depending on multiple others
         Bin Foo Bar

         # We can use different seperators
         One:Two|Three-Four+Five=Six Seven

         # We can also use multiple non-word characters as seperators
         This&*&^*&File:  is& & & :::REALLY()Neat

       From the examples above, it should be easy to create your own files.

METHODS

       This documents the methods differing from the ordinary Algorithm::Dependency::Source
       methods.

   new $filename
       When constructing a new Algorithm::Dependency::Source::File object, an argument should be
       provided of the name of the file to use. The constructor will check that the file exists,
       and is readable, returning "undef" otherwise.
