# binaries.  One should pass it the _base_ name of the program
# to wrap (one would pass "AbiWord" to wrap "AbiWord-2.4" and 
# "AbiWord-2.4"), the install base of the tree and, optionally, the location
# of the machine-dependent binaries and scripts, and, optionally, an
# installation-only prefix.

# Examples:
#     makewrapper.sh AbiWord /usr/local/AbiSuite /usr/local/libexec/AbiSuite /tmp/package_root
#     makewrapper.sh AbiCalc /usr/local/AbiSuite /usr/local/libexec/AbiSuite
