nsL is a new C-like programming language for writing NSIS installation wizards (http://nsis.sourceforge.net). The nsL assembler takes nsL code and translates it into original NSIS script which can then be compiled.

    This is very useful plug-in because NSIS syntax is a little "low level". With this nsL you can write NSIS installers in C/Java similar language faster and the script is nice and well-arranged. It contains most common syntax like functions, conditions, calls and much more, But there are still some little bugs (no big deal) and lack of IDEs (I use nsL in combination with Visual Studio using Visual & Installer: unsigned-softworks.sk/visual-installer/index.html which is then only IDE for this language). I do not recommend nsL to beginners but to intermediate NSIS users.
