# by linking it from $HOME/bin. May be called as below to activate a
# version that was installed from the current directory using the
# command below:
#
# swipl-activate --installed
#
# This can be combined by setting the following in ~/.bashrc, which will
# install each configuration into a different directory.
#
# export SWIPL_INSTALL_PREFIX=$HOME/cmake/swipl/@builddir@
