=head1 DESCRIPTION |
19 |
|
20 |
This module is implementation of node API of Hyper Estraier. Since it's |
21 |
perl-only module with dependencies only on standard perl modules, it will |
22 |
run on all platforms on which perl runs. It doesn't require compilation |
23 |
or Hyper Estraier development files on target machine. |
24 |
|
25 |
It is implemented as multiple packages which closly resamble Ruby |
26 |
implementation. It also includes methods to manage nodes. |
