+# All attribute lengths are implicit, and are calculated automatically

+# Input is of the form:
+#
+# WORD ...
+#
+# The WORD is a keyword which indicates the format of the following text.
+# WORD is one of:
+#
+# raw - read the grammar defined below, and encode an attribute.
+# The grammer supports a trivial way of describing RADIUS
+# attributes, without reference to dictionaries or fancy
+# parsers
+#
+# encode - reads "Attribute-Name = value", encodes it, and prints
+# the result as text.
+# use "-" to encode the output of the last command
+#
+# decode - reads hex, and decodes it "Attribute-Name = value"
+# use "-" to decode the output of the last command
+#
+# data - the expected output of the previous command, in ASCII form.
+# if the actual command output is different, an error message
+# is produced, and the program terminates.
+#
+#
+# The "raw" input satisfies the following grammar:
+#
+# Identifier = 1*DIGIT *( "." 1*DIGIT )
+#
+# HEXCHAR = HEXDIG HEXDIG
+#
+# STRING = DQUOTE *CHAR DQUOTE
+#
+# TLV = "{" 1*DIGIT DATA "}"
+#
+# DATA = 1*HEXCHAR / 1*TLV / STRING
+#
+# LINE = Identifier DATA
+#
+# The "Identifier" is a RADIUS attribute identifier, as given in the draft.
+#
+# e.g. 1 for User-Name
+# 26.9.1 Vendor-Specific, Cisco, Cisco-AVPAir
