# Build sflphone rpm packages for Fedora 10 and openSUSE 11
# 1 - The SFLphone package must be build with a specific GnuPG key. Please contact us to have more information about that (<sflphoneteam@savoirfairelinux.com>)
# 2. The source code can be teched through anonymous http access. So no need of special access.
# 3. After having all the prerequisites, you can run  "build-rpm-package.sh" to build rpm packages for sflphone.

# Refer to http://www.sflphone.org for futher information
