Originally this was a small library of 300 lines that made loading simple settings from text files easier. The library has been used in every one of my projects since I wrote it, and I think it probably did 90% of the work in each program.
After writing several different scripting engines that simply wrapped to some of the functions provided by the library, I expanded it, adding a few more functions which decreased development time further. Instead of doing 90% of the work for me, this unit now does 99%!
It allows me to create robust programs with lots of potential to customise without much work at all.
Well, I think it's useful, and hope you do too! :-)
