+.I config
+to parse configuration files.
+Terminal symbols are shown all in upper case, literals
+are emboldened; optional clauses are enclosed in brackets, ``[''
+and ``]'';  zero or more instantiations are denoted with ``*''.

+Lexical Conventions
+.LP
+The terminal symbols are loosely defined as:
+.IP ID
+.br
+One or more alphabetics, either upper or lower case, and underscore,
+``_''.
+.IP NUMBER
+.br
+Approximately the C language specification for an integer number.
+That is, a leading ``0x'' indicates a hexadecimal value,
+a leading ``0'' indicates an octal value, otherwise the number is
+expected to be a decimal value.  Hexadecimal numbers may use either
+upper or lower case alphabetics.
+.IP FPNUMBER
+.br
+A floating point number without exponent.  That is a number of the
+form ``nnn.ddd'', where the fractional component is optional.
+.LP
+In special instances a question mark, ``?'', can be substituted for
+a ``NUMBER'' token.  This is used to effect wildcarding in device
+interconnection specifications.
+.LP
+Comments in configuration files are indicated by a ``#'' character
+at the beginning of the line; the remainder of the line is discarded.
+.LP
+A specification
+is interpreted as a continuation of the previous line
+if the first character of the line is tab.
