with your (or IBM's) permission, yes. I can email you some standard
legal stuff for this. Without your permission I think you (IBM) retain
copyright for new files. For changes to existing files, we have been
generally adding extra "Copyright 2002 user@xxxxxxxx" comments in-line
to acknowledge the contribution. For example, in src/pmdas/linux/pmda.c :
* kernel.all.uptime in hours
* contributed by "gilly" <gilly@xxxxxxxxxx>
atom->ul = (u_long)(times(NULL)) / (proc_stat.hz * 60 * 60);

for one thing, the open source PCP libraries are LGPL. Non-library code
is GPL. In the past we have obtained permission from the original
copyright holder to use their code, e.g. see the comments at the
head of src/libpcp_http/src/http_lib.h for an example.
