translate from word list in a file


Is it possible to direct sed or tr to use a list of substitutions in a file? I realise that sed can pull a list of commands from a file, I am just trying to make it easier on the end user.

e.g.
Code:
'#MyVarName1' 'Logic.Values.Digital01'
'#MyVarName2' 'System.Stats.Resets.Count'
is a much easier file for the user to edit, instead of ...
Code:
s/'#MyVarName1'/'Logic.Values.Digital01'/g
s/'#MyVarName2'/'System.Stats.Resets.Count'/g
easier to read too...

You can have a script that reads the file and then uses a "for" loop to put each consecutive item into a sed statement.

Even simpler is the -f option in sed, in which it reads its info from a file.

Here is my favorite sed tutorial: http://www.grymoire.com/Unix/Sed.html
