+.TH COMPILE_ET 1 "22 Nov 1988" SIPB
+.SH NAME
+compile_et \- error table compiler
+.SH SYNOPSIS
+.B compile_et
+file
+.SH DESCRIPTION
+.B Compile_et
+converts a table listing error-code names and associated messages into
+a C source file suitable for use with the
+.IR com_err (3)
+library.
+
+The source file name must end with a suffix of ``.et''; the file
+consists of a declaration supplying the name (up to four characters
+long) of the error-code table:
+
+.B error_table
+.I name
+
+followed by up to 256 entries of the form:
+
+.B error_code
+.I name,
+"
+.I string
+"
+
+and a final
+
+.B end
+
+to indicate the end of the table.
+
+The name of the table is used to construct the name of a subroutine
+.I initialize_XXXX_error_table
+which must be called in order for the
+.I com_err
+library to recognize the error table.
+
+The various error codes defined are assigned sequentially increasing
+numbers (starting with a large number computed as a hash function of
+the name of the table); thus for compatibility it is suggested that
+new codes be added only to the end of an existing table, and that no
+codes be removed from tables.
+
+The names defined in the table are placed into a C header file with
+preprocessor directives defining them as integer constants of up to
+32 bits in magnitude.
+
+A C source file is also generated which should be compiled and linked
+with the object files which reference these error codes; it contains
+the text of the messages and the initialization subroutine.  Both C
+files have names derived from that of the original source file, with
+the ``.et'' suffix replaced by ``.c'' and ``.h''.
+
+A ``#'' in the source file is treated as a comment character, and all
+remaining text to the end of the source line will be ignored.
+
+.SH BUGS
+
+Since
+.B compile_et
+uses a very simple parser based on
+.IR yacc (1),
+its error recovery leaves much to be desired.
+
+.\" .IR for manual entries
+.\" .PP for paragraph breaks
+
+.SH "SEE ALSO"
+com_err (3).
