In spite of there being considerable documentation sometimes in the
config file, we go with CC0 because we don't want the notion of
'derived work' of a config file.
The example `settings.conf` is also CC0. Add some docs to
it while we're at it.
- Re-build the structures for doing value-checks, is now more tree-like.
- Document pointer ownership.
- Introduce wildcard matches ("*")
- Don't drop empty command-lists, since they can be used to avoid
wildcard matches. (E.g. "in this case, do nothing, but don't
fall through to wildcard").
- For both shellprocess and contextualprocess, add a top-level key
"timeout" that defaults to 10 seconds (which it already did).
- Allows setting "global" timeout for command-lists, while still
allowing individual timeouts per-command.
- Setting timeout per global variable in contextualprocess is not
supported; that would restrict the possible space of comparisions,
while not supporting a global setting timeout seems reasonable enough.
Use instances if you need wildly variable timeouts and don't want to
set them individually.
Allow running one or more commands based on the value of
a global configuration variable. This could, of course,
be done in a Python module with some custom code,
but for simple cases this is more straightforward
to configure through module instances.
Uses the CommandList developed for the ShellProcess
module to do the actual work.
FIXES#874
This is meant to run one or more jobs based on specific global
configuration values; if could also be done by a Python
module with just some if's, but this one can be used with
just the config file and covers a bunch of use-cases.
