########## sync
# for use with the test framework; push local stuff on a test node
# howto use: go on testmaster in the build you want to use and just run
# $ exp
# cut'n paste the result in a terminal in your working dir, e.g. (although all are not required)
# $ export BUILD=2013.07.02--lxc18
# $ export PLCHOSTLXC=gotan.pl.sophia.inria.fr
