+.II "table^convert to sed commands"
+The command
+.B tabletosed
+converts a two-column
+.I table
+into a file of
+.B sed
+statements that can be input to the
+.B sed
+stream editor.
+.B sed
+macros are in the form:
+.DM
+	s/old/new/g
+.DE
+.PP
+.B sed
+can do many things, including word-for-word substitution.
+.I sedfile
+produced is used by the
+.B /rdb
+command
+.BR translate .
+It can be used for language translation (in a stiff, inflexible way)
+and for other conversions of data bases.
+.SH Example
+Suppose we have a simple translation table, called
+.BR ed.t "
+.DM
+English Deutch
+------- -------
+I       Ich
+love    liebe
+you     dich
+widgit  
+.DE
+.PP
+The following command turns
+.B ed.t
+into a file of
+.B sed
+editing instructions, called
+.BR ed.sed.1 :
+.DM
+	tabletosed < ed.t > ed.sed.1
+.DE
+.PP
+.B ed.sed.1
+appears as follows:
+.DM
+	s/I/Ich/g
+	s/love/liebe/g
+	s/you/dich/g
+.DE
+.PP
+We can now use
+.B ed.sed.1
+with
+.B sed
+or
+.BR translate .
+For example, if file
+.B text
+contains the sentence
+.DM
+	I love you.
+.DE
+.PP
+then typing
+.DM
+	sed -f ed.sed.1 text
+.DE
+.PP
+prints the following on the standard output:
+.DM
+	Ich liebe dich.
+.DE
+.PP
+You can also use this command to construct form letters.
