+# 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.
+#
+# NOTE: I use `:' as the delimiter (by default) between the library soname
+# and any library version info.  This is because IRIX libraries (even
+# system libraries) have "version information" in both the soname and the
+# internal version field, so it's important to be able to separate those
+# fields.  If we just used `.', we wouldn't know where the soname ends and
+# the version infromation begins.
+#
+# On IRIX, use `elfdump -Dl' to find what libraries are required by
+# an executable.  `elfdump -L' does what we need too, but it gives us more
+# than we really need.
+#
+# Example `elfdump -Dl' output:
+#
+#$elfdump -Dl /usr/bin/X11/xterm
