 * This file search in the current node global node_module directory
 * for symbolic link that were not converted to windows version and
 * fix them. It can be useful to track the files that are modified
 * (the program will output a log of the binding symbolic links edited)
 * 
 * USAGE: node npm_windows_fix.js
 * Make sure to use the correct version of node you are interested
 * to inspect (e.g. nvm use x.x.x and then run this program)

Beautiful fix for the nvm problem!
