#
# The 'expression' module currently has no configuration.
#
# This module is useful only for 'xlat'. To use it,
# put 'expr' into the 'instantiate' section. You can then
# do dynamic translation of attributes like:
#
# Attribute-Name = `%{expr:2 + 3 + %{exec: uid -u}}`
#
# The value of the attribute will be replaced with the output
# of the program which is executed. Due to RADIUS protocol
# limitations, any output over 253 bytes will be ignored.
#
# The module also registers a few paircompare functions
