find all global packages, list them by directory


one module to rule them all, one module to find them, one module to bring them all

and in the darkness, lexically bind them

find all globally installed packages, resolving to a list of directories representing global packages.

var findGlobal = require('find-global-packages')
findGlobal(function(errdirs) {
  // dirs will be a list of strings representing 
  // paths to globally installed packages. 

Takes a single node-style callback, resolves to either an error or a list of directories. Directories are vetted by the presence of a file called package.json (but not its contents).
