Usage: ./bootstrap [options] PKG_ROOT [PKG_DIR]
PKG_ROOT is an URI, either of the form proto://host/path, or just /path
Note: The path must be absolute, it may not contain a literal ~
PKG_DIR is the path where caretaker and all further packages will be installed,
by default $default_path
Options:
--pkglist-cgi URL
Get the package list from URL - most useful with a git:// PKG_ROOT
