+#!/bin/bash
+
+#   split multi-key files into separate keys like ssh-authkeys likes
+
+# WHY
+# ---
+#
+# Yeah I wonder that too, when it's so much more maintainable to keep the damn
+# keys as sitaram@home.pub and sitaram@work.pub or such.  But there's no
+# accounting for tastes, and some old fogies apparently want to put all of a
+# user's keys into a single ".pub" file.
+
+# WARNINGS AND CAVEATS
+# --------------------
+#
+# - assumes no "@" sign in basenames of any multi-key files (single line file
+#   may still have them)
+
+# - assumes you don't have a subdir in keydir called "__split_keys__"
+
+# SUPPORT
+# -------
+#
+# NONE.
+
+# USAGE
+# -----
+#
+# to enable, uncomment the 'ssh-authkeys-split' line in the ENABLE list in the
+# rc file.
+
