15 pkg --help
17 Create a package user for the purpose of compiling
18 a particular package.
20 The user will be created with user and group both
21 equal to the name you specify.
23 You will then be put into the user's home
24 directory where you may proceed with
25 compiling/installing the package.
27 If the user already exists, this is equivalent to
28 su --login package-name
