file in the directory containing the sources."

#============================================================================
# We'll override the src_unpack() function from the eclass. This is necessary
# due to the inclusion of optional patches in the sources. These cannot be
# applied until after the initial base WOLK patch has been applied which is
# a problem, given that the eclass checks for the validity of any patches.
