+# NAME
+#    mountiso.sh - Mount ISO files in Nautilus or the shell
+#
+# SYNOPSIS
+#    mountiso.sh [filenames]
+#
+# DESCRIPTION
+#    Copy script to ~/.gnome2/nautilus-scripts/ and either:
+#    - right-click one / several ISO files and select Scripts -> mountiso.sh
+#    - run it in a shell as described above
+#
+#    In addition to mounting the ISO files, it will create a symlink from
+#    /path/to/iso (without file extension) to the mount point, for easy access.
