        <readme>
Downloads the precompiled 32bit Linux, 64bit Linux, or Mac OS X MUSCLE
binaries, which is faster than performing a local compilation,
avoids any issues with build dependencies, and is more reproducible between
installations as there is no variability from the compiler or library 
versions.
If the download attempt fails, compiling MUSCLE from source is attempted.
