NASM, the Netwide Assembler. Many many developers all over the net respect NASM for what it is - a widespread (thus netwide), portable (thus netwide!), very flexible and mature assembler tool with support for many output formats (thus netwide!!). Now we have good news for you: NASM is licensed under LGPL. This means its development is open to even wider society of programmers wishing to improve their lovely assembler. The NASM project is now situated at SourceForge.net, the most famous Open Source development center on The Net. Visit our development page at http://nasm.2y.net/ and our SF project at http://sf.net/projects/nasm/ See the file CHANGES for the description of changes between revisions. With best regards, NASM crew.
