"You don't." ;)
(as quoted from
http://stackoverflow.com/questions/1797455/how-to-put-license-agreement-in-spec-file-rpm
)
Eric mentioned another stackoverflow URL, too.

Note that shell archive (shar-style) package generators (STGZ, STBZ2 etc.)
do have a license acknowledge step, though.


If you do feel the urge to add this to an explicitly automation-capable
mechanism (e.g. RPM), then definitely make sure to check for
non-interactive shell environment, as Eric said.

Philosophically spoken you could say that since you need to prevent
non-interactive installs from getting blocked, this means that one user group
will be prompted, whereas another user group (with installation carried
out automatically) will not have any license acknowledgement step.
IOW, this strongly hints at RPM install step being the wrong place
to do such things.

HTH,
