organizing extensions/applications

[Geoff Savage <savage@fnal.gov>]

Hi,

One of my current confusions with EPICS is how to organize 
extension/application software developed here at Fermilab and downloaded 
from other sites.  I'm wondering how other sites tackle this issue.  Do 
we need to specify a standard way to package our work for distribution?

One particular thing I have noticed is with extensions.  Each extension 
often includes extensions/Makefile and extensions/src/Makefile.  When I 
unpack a new extension with these makefiles included I lose any changes 
I have made to the versions on disk.  This also includes overwriting 
R3.14 makefiles with R3.13 makefiles.  Comments?

Thanks in advance.

Geoff
