# this package contains the daemon version of dropbox

# note: the resulting program has to be invoced as
# 'dropbox' because the internal python engine takes
# uses the name of the program as starting point.

# Dropbox ships with its own copies of some libraries.
# Unfortunately, upstream makes changes to the source of
# some libraries, rendering them incompatible with the
# open-source versions. Wherever possible, we must try
# to make the bundled libraries work, rather than replacing
# them with our own.
