# find-provides is part of RPM, the Red Hat Package Manager. find-provides
# reads a list of full pathnames (in a package) on stdin, and outputs all
# shared libraries provided by (contained in) the package.
#
#
# On Digital/Tru64 Unix (OSF1), use `odump -D' to find what libraries a
# package provides. Note that Tru64 Unix 5.x and later come with `ldd',
# but sticking with `odump' works with versions of the OS back to at least
# 3.x, so it's the preferred method.
#
# Example `odump -D' output:
#
#$odump -D /usr/shlib/libc.so
