[Buildbot-devel] Adding interpolated property in a build step

[Alexander Sack]

Hello:

I have read that build steps can set properties.  I'd like to have a
step set a build property that will be interpolated at run-time and
then re-used by another build step.

Step X - create a file based on some interpolated properties, save the
filename which is based on interpolated values in the build
Step Y - use filename property

The doc talks about setting shell based env and command based output.
But how do I set a simple property from within a build step?  And can
I use WithProperties()?

Cheers,
