This is an embryonic library of routines which will read, write, and seek on arbitrary Unix streams such as pipes and URLs. The most important thing is the seek capability, which allows you to address any point in the stream with random access rather than sequential access. At present, only Unix pipes are accessible. The current implementation is to store the contents of the Unix pipe in a temporary cache file. All of the routines are required, and you may wish to download the entire archive in one file as either a gzip'ed tar file or zip file .
