+# /etc/init.d/dphys-swapfile - automatically set up an swapfile
+# author Neil Franklin, last modification 2006.09.15

+
+# this init.d script is intended to be run from rcS.d
+#   must run after  mount  of  /var  which may only happen in  S35mountall.sh
+#     for this reason we can not build swapfile until after  S35mountall.sh
+#       so we also need to use  init.d start|stop  to swapon|off our file
+#   and sensibly before the lots of stuff which may happen in  S40networking
+#   so we run it as rcS.d/S37dphys-config

+# Short-Description: Autogenerate and use a swap file
+# Description:       This init.d script exists so one does not need to have a fixed size
+#                    swap partition. Instead install without swap partition and then run
+#                    this, with file size (re-)computed automatically to fit the current
+#                    RAM size.
