axhtpasswd is used to help manually edit .htpasswd files, used by axhttpd This file is formatted as the
familiar colon-separated username/encrypted-password pair, records delimited by newlines. The program
reads the username from command line and the password from input, outputs the username/encrypted-password
pair then exits.
The encryption of this password uses a proprietary algorithm due to the dependency of many crypt
libraries on DES, so the generated .htpasswd is not portable among other HTTPDs.
