+.II "table^convert to m4"
+.II m4
+The command
+.B tabletom4
+converts a two-column table into a file of
+define statements that can be input to the COHERENT macro processor
+.BR m4 .
+Define macros are in the form
+.I define(old,new).
+.PP
+.B m4
+can do many things, including word-for-word substitution.
+It can be used for language translation (in a stiff, inflexible way)
+and for other conversions of data bases.
+.PP
+The
+.I definefile
+that
+.B tabletom4
+produces is required by the
+.B /rdb
+command
+.BR translate .
+Only words that have a corresponding translation in the second
+column will be put into
+.IR definefile .
+In this way, you can
+use the file before you have all of the translations entered.
+.SH Example
+Consider the simple translation table
+.BR ed.t :
+.DM
+English Deutch
+------- -------
+I       Ich
+love    liebe
+you     dich
+widgit  
+.DE
+.PP
+The following command converts
+.B ed.t
+to m4 format and writes its output into file
+.BR ed :
+.DM
+	tabletom4 < ed.t > ed
+.DE
+.PP
+.B ed
+now contains the following:
+.DM
+define(I,Ich)
+define(love,liebe)
+define(you,dich)
+.DE
+.PP
+Note that
+.B widgit
+was not converted because it did not have
+a translation string in the second column of the table.
+.B ed
+can now be used by
+.B m4
+or
+.BR translate .
+For example, if file
+.B text
+contains the following:
+.DM
+	I love you.
+.DE
+.PP
+The command
+.DM
+	m4 ed text
+.DE
+.PP
+writes
+.DM
+	Ich liebe dich.
+.DE
+.PP
+onto the standard output.
