# acme-dia
|
||||
|
||||
Programs for previewing diagrams from acme.
|
||||
|
||||
- `Uml` accepts PlantUML input, renders the diagram, and passes the result to the `plumber` for preview.
|
||||
|
||||
Perhaps others programs in the future.
|
||||
|
||||
# Usage
|
||||
|
||||
Highlight the diagram text in an acme window. 2-1 chord it to `Uml`.
