 1 Obtaining Yhc
Either download a binary distribution, or compile it from source (see Yhc/Building). A binary distribution is probably easier, but there aren't any yet until the first release.
 2 Setting the Package Path
You can either set YHC_BASE_PATH to something so that "%YHC_BASE_PATH%/bin/yhc" will run Yhc, typically the location of the inst folder if you are running from the source tree.
Alternatively, you can add your yhc executable to the PATH, and Yhc will find the other bits automatically.
 3 Compiling Hello World
Take a sample file, HelloWorld.hs
=========== File HelloWorld.hs ===============
module Main where
main = putStrLn "Hello, World!\n"
$ yhc HelloWorld $ yhi HelloWorld Hello, World!
 3.1 yhc
The yhc command takes a haskell source file, and generate a haskell bytecode file (extension, .hbc). The program always runs in make mode - so it will compile all requirements automatically.
 3.2 yhi
The yhi command runs a haskell byte code file.
 3.3 yhe
Yhe provides a Haskell 'command line' powered by Yhc. A gtk GUI also exists.
