Next round of install script cleanup -- we now create +FILES,

+RCD_SCRIPTS, and +PERMS subscripts to handle copying config files
and rc.d scripts, and setting special permissions on files.  The +FILES
and +RCD_SCRIPTS are basically identical except for different embedded
packets of data, and they feature reference-counting for the files in
case multiple packages share the same config file.

Garbage-collect unused functions and definitions in the install scripts
now that the subscripts are self-contained.

+#        ./+FILES VIEW-REMOVE depotdir viewdir
+#        ./+FILES CHECK-ADD|CHECK-REMOVE [metadatadir]
+#
+# This script supports two actions, ADD and REMOVE, that will add or
+# remove the configuration files needed by the package associated with
+# <metadatadir>.  The CHECK-ADD action will check whether any files
+# needed by the package are missing, and print an informative message
+# noting those files.  The CHECK-REMOVE action will check whether
+# any files needed by the package still exist, and print an informative
+# message noting those files.  The CHECK-ADD and CHECK-REMOVE actions
+# return non-zero if they detect either missing or existing files,
+# respectively.  The VIEW-REMOVE action will remove from <viewdir> the
+# links to the configuration files in <depotdir>.
+#
+# Lines starting with "# FILE: " are data read by this script that
+# name the files that this package requires to exist to function
+# correctly, along with the locations of the example files, e.g.
+#
+#	# FILE: /etc/bar.conf c /example/bar.conf
+#	# FILE: /etc/baz/conf c /example/baz.conf 0600 foo-user foo-group
