Added information on how input and output files are selected.

Added information on where files are located by llvm-link.
Added missing options.
Re-worded some stuff so that it (hopefully) sounds better.

DESCRIPTION
</h3>
The llvm-link command takes several LLVM bytecode files and links them together into a single LLVM bytecode file.
The llvm-link command takes several LLVM bytecode files and links them together
into a single LLVM bytecode file. It writes the output file to standard
output, unless the -o option is used to specify a filename.
<p>
The llvm-link command attempts to load the input files from the current
directory. If that fails, it attempts to locate each file within the
directories specified by the -L options on the command line. The library
search paths are global; each one is search for every input file if necessary.
The directories are searched in the order they were specified on the command
line.

DESCRIPTION
</h3>
The opt command is the LLVM optimizer. It takes LLVM bytecode as input, runs
the specified optimizations on it, and then outputs the optimized code in LLVM
the specified optimizations on it, and then outputs the optimized LLVM
bytecode.
<p>
The optimizations available via opt depend upon what libraries it was linked
with, as well as any additional libraries that have been loaded with the -load
option. Use the -help option to determine what optimizations you can use.

<p>
If no filename is specified on the command line, opt reads its input from
standard input.
<p>
If an output filename is not specified with the -o option, opt writes its
output to the standard output.
