- refactor the elevation detection stuff. I'm not terribly happy with it.

- add generic password prompt func that takes in a `prompt []byte` param and returns `(passwd []byte, err error)`
```
func getPasswd(prompt []byte) (passwd []byte, err error) {

        var b []byte
        var newLnd bool
        var origIn *term.State
        var origOut *term.State
        var fdIn int = int(os.Stdin.Fd())
        var fdOut int = int(os.Stdout.Fd())

        if origIn, err = term.GetState(fdIn); err != nil {
                return
        }
        if origOut, err = term.GetState(fdOut); err != nil {
                return
        }
        defer func() {
                var tErr error

                if !newLnd {
                        fmt.Println()
                }

                if tErr = term.Restore(fdIn, origIn); tErr != nil {
			return
                }
                if tErr = term.Restore(fdOut, origOut); tErr != nil {
			return
                }
        }()

	os.Stdout.Write(prompt)
        if b, err = term.ReadPassword(fdIn); err != nil {
                return
        }
        passwd = b
        fmt.Println()
        newLnd = true

        return
}
```


- password generator/hash+salter and "checksum/hash guesser" utility/library
-- incorporate with r00t2.io/pwgen
-- incorporate with https://github.com/tredoe/osutil ?
-- cli flag to dump flat hashes too (https://github.com/hlandau/passlib and others soon in pwgen)

- auger needs to be build-constrained to linux.
-- (i think i fixed this)

- unit tests

- constants/vars for errors

- func and struct to return segregated system-level env vars vs. user env vars (mostly usable on windows) (see envs/.TODO.go.UNFINISHED)

- validator for windows usernames, domains, etc. (for *NIX, https://unix.stackexchange.com/a/435120/284004)
