This script is intended to execute a single build target. This script should be
|
||
|
|
called by ninja, passing the port, ninja dir, and build target via arguments.
|
||
|
|
The script then executes a simple get request to the scons daemon which is listening
|
||
|
|
on from localhost on the set port.
