spec2ophyd#

Read SPEC config file and convert to ophyd setup commands.

This is a tool to help migration from SPEC to bluesky. It reads the SPEC configuration file provided on the comand line and converts the lines it recognizes into ophyd commands which create ophyd objects. These commands are printed to sys.stdout. The output can be copied into a setup file for ophyd.
