+# If you have java installed in a non-standard location, you can set
+# the path to it by uncommenting the following line:
+#    export JAVA=/usr/bin/java
+
+# If you want to copy one or more files or directories to the target disk
+# image, add the root directory to this variable.  All files will be
+# copied from the source to the target using the same path from the source.
+#
+# For example, if you set COPYDIRS to dir and in your project you have
+# the following files:
+#     dir/mySystemFile
+#     dir/newDir/anotherFile
+#
+# Then, during the copy phase, mySystemFile will be copied into the root
+# of the disk and anotherFile will be copied into a directory named
+# newDir.  The newDir directory will be created if it does not already
+# exist.
+#
+# The name of the file to copy is checked and if it ends in:
+#     .as - It assumes the file is in AppleSingle format.  The .as
+#           suffix is stripped from the name when copied to the
+# 	    disk image.
+# .<char> - If the file ends with a single character which matches
+#           a DOS 3.3 file type (A, B, T, etc) it uses that value as
+#           the file type of the file copied to the disk image.  The
+#           single character is removed from the file name.
+#  .<TLA> - If the file ends with a three letter alpha extension, it
+#           uses that TLA as the file type of the file copied to the
+#           disk image.  The TLA is removed from the file name.
+#
+# If you do not provide any type information for your filenames,
+# it will be copied as a binary.

+# You should generate these files in the $(GENDIR) directory or
