# ${CALC_SHAREDIR}	where to install calc help, .cal, startup, config files
#
# NOTE: The install rule prepends installation paths with ${T}, which
#	by default is empty.  If ${T} is non-empty, then installation
#	locations will be relative to the ${T} directory.

# T - top level directory under which calc will be installed
#
# The calc install is performed under ${T}, the calc build is
# performed under /.	The purpose for ${T} is to allow someone
# to install calc somewhere other than into the system area.
#
# For example, if:
#
#     BINDIR= /usr/bin
#     LIBDIR= /usr/lib
#     CALC_SHAREDIR= /usr/share/calc
#
# and if:
#
#     T= /var/tmp/testing
#
# Then the installation locations will be:
#
#     calc binary files:	/var/tmp/testing/usr/bin
#     calc link library:	/var/tmp/testing/usr/lib
#     calc help, .cal ...:	/var/tmp/testing/usr/share/calc
#     ... etc ...		/var/tmp/testing/...
#
# If ${T} is empty, calc is installed under /, which is the same
# top of tree for which it was built.  If ${T} is non-empty, then
# calc is installed under ${T}, as if one had to chroot under
# ${T} for calc to operate.

# just execute calc show builtin, but calc may not have been built or
# buildable at this point.  The hack-a-round used is to convert ../func.c
# into a standalone program that generates a suitable function list
# that is standwiched between the top and bottom builtin help text.
#
# We form funclist.c by sedding out unwanted stuff from builtins table,
# converting NUMBER* and VALUE into harmless types and converting
# the showbuiltins() function into main().  Combined with the -DFUNCLIST
# we will avoid all of the complex calc types, macros and defines and
# be left with just main() and a mininal builtins table.
