# find-requires is part of RPM, the RedHat Package Manager. find-requires
# reads a list of full pathnames (in a package) on stdin, and outputs all
# shared libraries the package requires to run correctly.
#
# On HP-UX, use `chatr' to find the library dependencies for an executable
#
# Example chatr output:
#
#$chatr /usr/bin/chatr
#/usr/bin/chatr:
# shared executable
# shared library dynamic path search:
# SHLIB_PATH disabled second
# embedded path disabled first Not Defined
# internal name:
# chatr
# shared library list:
# dynamic /usr/lib/libc.1
# shared library binding:
# deferred

#
# TVM: it might be better to re-write this so that `file' isn't used, since
# it can all be done with `chatr' (note the second line of chatr output tells
# whether it's a shared executable or not), but this works.
