| 12 | ||||
| 13 | use Text::Abbrev; | |||
| 14 | abbrev $hashref, LIST | |||
| 15 | ||||
| 16 | ||||
| 17 | =head1 DESCRIPTION | |||
| 18 | ||||
| 19 | Stores all unambiguous truncations of each element of LIST | |||
| 20 | as keys in the associative array referenced by C<$hashref>. | |||
| 21 | The values are the original list elements. | |||
| 22 | ||||

| 27 | %hash = abbrev qw(list edit send abort gripe); | |||
| 28 | ||||
| 29 | abbrev $hashref, qw(list edit send abort gripe); | |||
| 30 | ||||
