/* Events */
process.on('exit', function(code) {}) // Emitted when the process is about to exit
process.on('uncaughtException', function(err) {}) // Emitted when an exception bubbles all the way back to the event loop. (should not be used)
/* Properties */
process.stdout // A writable stream to stdout.
process.stderr // A writable stream to stderr.
process.stdin // A readable stream for stdin.
process.argv // An array containing the command line arguments.
process.env // An object containing the user environment.
process.execPath // This is the absolute pathname of the executable that started the process.
process.execArgv // This is the set of node-specific command line options from the executable that started the process.
process.arch // What processor architecture you're running on: 'arm', 'ia32', or 'x64'.
process.config // An Object containing the JavaScript representation of the configure options that were used to compile the current node executable.
process.pid // The PID of the process.
process.platform // What platform you're running on: 'darwin', 'freebsd', 'linux', 'sunos' or 'win32'.
process.title // Getter/setter to set what is displayed in 'ps'.
process.version // A compiled-in property that exposes NODE_VERSION.
process.versions // A property exposing version strings of node and its dependencies.
process.maxTickDepth // Callbacks passed to process.nextTick will usually be called at the end of the current flow of execution, and are thus approximately as fast as calling a function synchronously.
/* Methods */
process.abort() // This causes node to emit an abort. This will cause node to exit and generate a core file.
process.chdir(dir) // Changes the current working directory of the process or throws an exception if that fails.
process.cwd() // Returns the current working directory of the process.
process.exit([code]) // Ends the process with the specified code. If omitted, exit uses the 'success' code 0.
process.getgid() // Gets the group identity of the process.
process.setgid(id) // Sets the group identity of the process.
process.getuid() // Gets the user identity of the process.
process.setuid(id) // Sets the user identity of the process.
process.getgroups() // Returns an array with the supplementary group IDs.
process.setgroups(grps) // Sets the supplementary group IDs.
process.initgroups(user, extra_grp) // Reads /etc/group and initializes the group access list, using all groups of which the user is a member.
process.kill(pid, [signal]) // Send a signal to a process. pid is the process id and signal is the string describing the signal to send.
process.memoryUsage() // Returns an object describing the memory usage of the Node process measured in bytes.
process.nextTick(callback) // On the next loop around the event loop call this callback.
process.umask([mask]) // Sets or reads the process's file mode creation mask.
process.uptime() // Number of seconds Node has been running.
process.hrtime() // Returns the current high-resolution real time in a [seconds, nanoseconds] tuple Array./* Properties */
path.sep // The platform-specific file separator. '\\' or '/'.
path.delimiter // The platform-specific path delimiter, '' or ':'.
/* Methods */
path.normalize(p) // Normalize a string path, taking care of '..' and '.' parts.
path.join([path1], [path2], [...]) // Join all arguments together and normalize the resulting path.
path.resolve([from ...], to) // Resolves 'to' to an absolute path.
path.relative(from, to) // Solve the relative path from 'from' to 'to'.
path.dirname(p) // Return the directory name of a path. Similar to the Unix dirname command.
path.basename(p, [ext]) // Return the last portion of a path. Similar to the Unix basename command.
path.extname(p) // Return the extension of the path, from the last '.' to end of string in the last portion of the path.
