Editing Launching From a Script (section)

== Usage ==
With PyMOL 2.1, calling any pymol.cmd function will automatically start a backend process without the GUI in the main thread. "finish_launching" should not be necessary, and will launch PyMOL in a new thread with an event loop, which will cause 100% CPU usage (at least with "-c").

<source lang="python">
from pymol import cmd
cmd.fragment('ala')
cmd.zoom()
cmd.png('/tmp/test.png', 300, 200)
</source>

Since PyMOL 1.7.4, the following form is sufficient:

''This is not supported on macOS (see [https://github.com/schrodinger/pymol-open-source/issues/28 bug report])''

<source lang="python">
import pymol
pymol.finish_launching(['pymol', '-q'])
</source>

Before 1.7.4, either "-K" was needed as an additional argument, or arguments had to be assigned to __main__.pymol_argv or pymol.pymol_argv.
