if somebody is interested in something else than ''normal regular 
expressions'' (where normal is awk, sed, posix, perl, etc) i can recommend

it is regexp for the scheme shell. it has s-expressions instead of 
strings. i find it easier to use when the regular expression goes beyond 
that which is possible to do with strstr and friends.

Those were the days...

    solely in a computer program then the subject matter is not
    patentable in whatever manner it may be presented in the claims."
