JWlink general info

JWlink is a linker for x86 that can create 16-, 32- and 64-bit binaries. It's a modified Open Watcom Wlink. Some features have been added and a few bugs have been fixed. Generally, it has been made more compatible with the MS linker (the cmdline syntax is still quite different).

Besides JWlink's source code there are also precompiled binaries available for Windows, DOS and Linux. The packages containing precompiled binaries also include a Manual (in HtmlHelp format for Windows, else in plain Html).
