# find-requires is part of RPM, the Red Hat Package Manager. find-requires
# reads a list of full pathnames (in a package) on stdin, and outputs all
# shared libraries the package requires to execute.
#
# On Digital/Tru64 Unix (OSF1), use `odump -Dl' to find the library
# dependencies for an executable. `odump -D' does most of what we need,
# but it doesn't give us library version information, so you must use
# `odump -Dl'. Note that Tru64 5.x and on have `ldd', but this works just
# as well, and works on older versions of the OS.
#
# Example `odump -Dl' output:
#
#$odump -Dl /usr/bin/X11/xterm
