+# osenv
+
+Look up environment settings specific to different operating systems.
+
+## Usage
+
+```javascript
+var osenv = require('osenv')
+var path = osenv.path()
+var user = osenv.user()
+// etc.
+
+// Some things are not reliably in the env, and have a fallback command:
+var h = osenv.hostname(function (er, hostname) {
+ h = hostname
+})
+// This will still cause it to be memoized, so calling osenv.hostname()
+// is now an immediate operation.
+
+// You can always send a cb, which will get called in the nextTick
+// if it's been memoized, or wait for the fallback data if it wasn't
+// found in the environment.
+osenv.hostname(function (er, hostname) {
+ if (er) console.error('error looking up hostname')
+ else console.log('this machine calls itself %s', hostname)
+})
+```
+
+## osenv.hostname()
+
+The machine name. Calls `hostname` if not found.
+
+## osenv.user()
+
+The currently logged-in user. Calls `whoami` if not found.
+
+## osenv.prompt()
+
+Either PS1 on unix, or PROMPT on Windows.
+
+## osenv.tmpdir()
+
+The place where temporary files should be created.
+
+## osenv.home()
+
+No place like it.
+
+## osenv.path()
+
+An array of the places that the operating system will search for
+executables.
+
+## osenv.editor()
+
+Return the executable name of the editor program. This uses the EDITOR
+and VISUAL environment variables, and falls back to `vi` on Unix, or
+`notepad.exe` on Windows.
+
+## osenv.shell()
+
+The SHELL on Unix, which Windows calls the ComSpec. Defaults to 'bash'
+or 'cmd'.
