DESCRIPTION

13       Algorithm::Dependency::Source::File implements a source where the items
14       are stored in a flat file or a relatively simple format.
15
16   File Format
17       The file should be an ordinary text file, consisting of a series of
18       lines, with each line completely containing the information for a
19       single item.  Blank lines, or lines beginning with the hash character
20       '#' will be ignored as comments.
21
22       For a single item line, only word characters will be used. A 'word
23       character' consists of all letters and numbers, and the underscore '_'
24       character.  Anything that is not a word character will be assumed to be
25       a separator.
26
27       The first word will be used as the name or id of the item, and any
28       further words in the line will be used as other items that this one
29       depends on. For example, all of the following are legal.
30
31         # A single item with no dependencies
32         Foo
33
34         # Another item that depends on the first one
35         Bar Foo
36
37         # Depending on multiple others
38         Bin Foo Bar
39
40         # We can use different separators
41         One:Two|Three-Four+Five=Six Seven
42
43         # We can also use multiple non-word characters as separators
44         This&*&^*&File:  is& & & :::REALLY()Neat
45
46       From the examples above, it should be easy to create your own files.

METHODS

49       This documents the methods differing from the ordinary
50       Algorithm::Dependency::Source methods.
51
52   new $filename
53       When constructing a new Algorithm::Dependency::Source::File object, an
54       argument should be provided of the name of the file to use. The
55       constructor will check that the file exists, and is readable, returning
56       "undef" otherwise.
