# Two things happen when this package gets built and installed:
#   1. The C source gets compiled into a library.
#   2. The C headers and the Ur interface files get stuck in a location where
#      Ur can find them.

# One file which needs to get generated at build-time is the config.urp
# configuration header, which provides Ur some build-time constants for users
# of the library.  Unfortunately, this can't be done purely with autoconf,
# because autoconf will not expand @includedir@ recursively.  Apparently, the
# supported way to do this is with (shudder) sed....  (For more information,
# see <http://stackoverflow.com/questions/1440873/>.)
