I'd use awk. I haven't experimented with mu-awk, but I suppose it's more
or less compatible to POSIX-awk. Splitting the input records at & and the
fields at = and +, and assuming that's all there is to it (I haven't
bothered to look up the complete syntax), here's a first effort:

If the file muff.cgi contains the one line


then the command line

awk 'BEGIN {
              RS="&"; FS="+|="
              for (i=1; i<NF; i++)
                 print $1 i "=" $(i+1)
           }' muff.cgi



If you pass that to a shell, it will set the values precisely like that.
Is that okay for a start?
