# Parameters:
# -d	      Installs all the needed compilation dependencies
# -r distro   Prepares a release for a given distro (jaunty, karmic, lucid...) in /tmp
#             After that, ***cd /tmp*** and upload with: dput -f meiga meiga*.changes
# -rn distro  The same than -r, but precompiling C sources to avoid dependancy on
#             Vala package in the target distro
# -s          Prepares a source release
# -sn         The same than -s, but precompiling C sources to avoid dependancy on
#             Vala package
