+# This file contains definitions of file types which will be created

+# If no definitions are found here, filetypes.h will be empty.
+# You should keep the defaults, though!
+
+# The syntax is very simple: Each line consists of one character,
+# representing a gopher file type, followed by file extensions
+# (without dots) of files to be handled as that gopher type.
+# Fields must be separated by TAB or SPC.
+# Empty lines and lines starting with a lone '#' are ignored.
+# (Do not use lines with several '###...' though! Stupid script!)
+# No more than MAX_FILETYPES (defined in gophernicus.h) extensions
