# This is a quick^Wslow dirty hack to check binaries and libraries for missing
# dependancies using ldd.  Only those files with missing dependancies (along
# with the missing library information itself) will be written to stderr.
# Redirecting stderr to a file is advised, since this can produce a large
# volume of output on a system with many missing libraries.
