package, which may be insufficient when needing a specific output of a
multiple-output package.
@item --install-from-file=@var{file}
@itemx -f @var{file}
Install the package that the code within @var{file} evaluates to.
As an example, @var{file} might contain a definition like this
(@pxref{Defining Packages}):
@example
@verbatiminclude package-hello.scm
@end example
Developers may find it useful to include such a @file{package.scm} file
in the root of their project's source tree that can be used to test
development snapshots and create reproducible development environments
(@pxref{Invoking guix environment}).
@item --remove=@var{package} @dots{}
@itemx -r @var{package} @dots{}
Remove the specified @var{package}s.
