# Run './libtool --help' for help with using this script from the
# command line.
## ------------------------------- ##
## User overridable command paths. ##
## ------------------------------- ##
# After configure completes, it has a better idea of some of the
# shell tools we need than the defaults used by the functions shared
# with bootstrap, so set those here where they can still be over-
# ridden by the user, but otherwise take precedence.

## -------------------------- ##
## Source external libraries. ##
## -------------------------- ##
# Much of our low-level functionality needs to be sourced from external
# libraries, which are installed to $pkgauxdir.
# Set a version string for this script.

# results into a variable named after the function, and often use
# temporary variables in the '^_G_' namespace. If you are careful to
# avoid using those namespaces casually in your sourcing script, things
