# match phpgw_vfs2*). I have created a class to handle mime types and one
# to handle the versioning system. Things can appear a litte weird
# sometimes, mostly because the operations in the versioning system are not
# atomic as they should be (and, for example, some database operation
# error can make the version table inconsistent with some sort of bugs.
