+# Instructions:
+# 'dm' will manage a list of id-directory. 'dmcd' will allow the current shell to
+# change to the directory given by 'id'.
+#
+# Examples:
+#  $ dm 1 /tmp   # Adds the id '1' for /tmp
+#  $ dm 2 .      # Adds the id '2' for the current dir
+#  $ dmcd 1      # Goes to /tmp
+#  $ dmcd 2      # Goes to what was your current dir
+#  $ dm -d 2     # Deletes the entry for '2'.
+#  $ dm          # Shows your 'database'
+#  1     /tmp
+#  $ dm -h       # Shows help, and defines 'dmcd' for sh.
+#
+# In order to use 'dmcd', you should define the function
+# given by "dm -h" in your shell. Put it in your bashrc or
+# a file like that.
+#
+# Your directory database is stored in ~/.dm .
