Include softIoc and other executables

[zhangt58]

Hi, I'm wondering if it's reasonable to distribute the tools like softIoc and softIocPVA with this package.
I'm using epicscorelibs together with pyepics and cothread, and it is great that I don't have to compile epics base, but in some cases, softIoc is wanted, if this package can provide, that would be wonderful!

Or I'm looking forward to a new package which is distributing EPICS tools via PyPI.

Try:

python -m epicscorelibs.ioc -h

https://github.com/mdavidsaver/epicscorelibs/blob/9974875f9cbddd68a3d8dcc358eb4dd6c38b95db/src/python/epicscorelibs/ioc.py#L102-L109

Thanks! Indeed, this command could be used to start up an IOC, but got the below timeout error, where I'm cothread.catools to update the PVs:

I can't replicate. I see:

$ cat cnt.db 
record(calc, "cnt") {
    field(CALC, "VAL+1")
    field(SCAN, "1 second")
}
$ python -m epicscorelibs.ioc -d cnt.db
