    11 pkg -- create a package user.

    13 syntax:

    14   pkg package-name description

    15   pkg --help 

    16   

    17 Create a package user for the purpose of compiling

    18 a particular package.

    19 

    20 The user will be created with user and group both

    21 equal to the name you specify.

    22 

    23 You will then be put into the user's home

    24 directory where you may proceed with

    25 compiling/installing the package.

    26 

    27 If the user already exists, this is equivalent to 

    28   su --login package-name
