@@ -38,6 +38,17 @@ Python-abp contains a script that can do this called `flrender`:
This will take the top level fragment in `fragment.txt`, render it and save into
`filterlist.txt`.
+The `flrender` script can also be used by only specifying `fragment.txt`:
+
+ $flrender fragment.txt
+
+in which case the rendering result will be sent to `stdout`. Moreover, when
+it's run with no positional arguments:
+
+ $flrender
+
+it will read from `stdin` and send the results to `stdout`.
+
Fragments might reference other fragments that should be included into them.
The references come in two forms: http(s) includes and local includes:
