USL is an object-oriented scripting language written with C++ and compiled on both Linux and Windows. Without a script provided, USL is an interactive interpreter and programmable command shell. There is no socket programming with USL. USL is intended for general purpose scripting in local systems.
I have added documentation to the archives at sourceforge.
I have added an HTML USL tutorial in the archived distribution files. The tutorial is very organized, simple to follow, and contains examples with highlighted syntax. The tutorial code be considered documentation but I'm not exactly sure on how to classify it. For those who were asking about documentation.
