#
# The Subversion bindings use this manually written proxy class approach
# to the Ruby bindings. Note that in C the struct svn_fs_t is an
# opaque pointer and the Ruby FileSystem proxy class is hand written around it.
# This testcase tests this and the C close function and subsequent error
# handling.
