# Script to build RPMs for RHEL from inside a git checkout.

# The following allows environment variables to override the target directories
#   the alternative is to have a file in your home directory calles .rpmmacros
#   containing the following:
#   %_topdir  /home/mylogin/redhat
#
# Note: Under this directory rpm expects to find the same directories
# that are under the /usr/src/redhat directory.

# extra options passed to rpmbuild
EXTRA_OPTIONS="$1"

RPMSPECDIR=`rpm --eval %_specdir`
RPMSRCDIR=`rpm --eval %_sourcedir`

# At this point the RPMSPECDIR and RPMSRCDIR variables must have a value!
