+# Encrypt and decrypt files using a fixed cipher and passphrase.
+# The first line of the (unencrypted) file is considered the "password",

+# Available commands:
+#       clip: copy the secret to clipboard; deleted after 10 seconds
+#       edit: edit or add a file
+#       show: show the full encrypted file

+# Requires: openssl, xsel (for clip only)
