    6 # pkgfoster is a simple script you can use to clean up orphaned packages (i.e. 
    7 # packages which no other package depends on). It uses prt-cache by default, so 
    8 # remember to build the cache with "prt-get cache". You can also use normal 
    9 # prt-get by modifying the PRT_GET variable. List of packages to keep 
   10 # are stored in ~/.keepers. Packages from core are never considered for 
   11 # deletion.
