I worte a library for a very fast random access tar files
could be used instead of parsing XML data and poping binray data from the arcive
it's very smart and even faster than .zip or MS Access DB
the idea is like the dictd zipped that generate indexed gz file
this reduce the efficiency but not much
for example lesaan al arab book was just about 7.3MB in this format
and it's very simple to pop the first, last,second memeber files in that order
while this is very slow even in uncompressed tar
the commpressing tool is not yet functional, I wrote a tool that
convert tar files to index bz2 tar files
