Like any other piece of software (and information generally),
cmd5checkpw comes with NO WARRANTY.

How to install:

 1. Edit conf-qmail, conf-man and include path to qmail and your man pages in here.

 2. Compile the program.
       % make

 3. Install the programs and man page:
       # make setup

Now you should have 

- cmd5checkpw binary in your '/bin' directory.
- cmd5checkpw man page in '/usr/local/man/man8'
- a sample of 'authuser' copied to your '/var/qmail/doc' directory 

Customization:

- Select a free user id in your system. 
- Include that user in '/var/qmail/users/authuser'
- You might want:
     "chown thatuser /var/qmail/users/authuser" , 
     "chmod 400 /var/qmail/users/authuser"
     "chown thatuser /bin/cmd5checkpw" and 
     "chmod a+s /etc/cmd5checkpw".

  Of course replace "thatuser" with username of the user you have created.
