36 |

|

37 |
|
|
* <pre> |
38 |
|
|
* Data::Lift - Pass data around between various "actors". |
39 |
|
|
* |
40 |
|
|
* These "actors" are kinda plugin-modules |
41 |
|
|
* lying at "locations" and actually mungle the data. |
42 |
|
|
* |
43 |
|
|
* "Locations" are by now: |
44 |
|
|
* x local filesystem |
45 |
|
|
* o remote anything |
46 |
|
|
* |
47 |
|
|
* The "actors" require (by now) to be native php classes |
48 |
|
|
* having a method "perform". Please have a look at others |
49 |
|
|
* lying in the Data::Lift namespace at org.netfrag.glib to |
50 |
|
|
* get a picture of how to implement own "actors". |
51 |
|
|
* </pre> |
