rlm@2 17 Create a package user for the purpose of compiling
rlm@2 18 a particular package.
rlm@2 19
rlm@2 20 The user will be created with user and group both
rlm@2 21 equal to the name you specify.
rlm@2 22
rlm@30 23 You will then be put into the user home
rlm@2 24 directory where you may proceed with
rlm@3 25 compiling/installing the package.
rlm@2 26
rlm@2 27 If the user already exists, this is equivalent to
rlm@3 28 su --login package-name
