Quickly looking at the manual for
tlmgr help) it lists
install [option...] pkg...
Install each pkg given on the command line, if it is not already
installed. It does not touch existing packages; see the "update" action
for how to get the latest version of a package.
By default this also installs all packages on which the given pkgs are
Nothing is actually installed; instead, the actions to be performed
are written to the terminal.
Instead of fetching a package from the installation repository, use
the package files given on the command line. These files must be
standard TeX Live package files (with contained tlpobj file).
If updates to "tlmgr" itself (or other parts of the basic
infrastructure) are present, "tlmgr" will bail out and not perform the
installation unless this option is given. Not recommended.
Do not install dependencies. (By default, installing a package ensures
that all dependencies of this package are fulfilled.)
Normally, when you install a package which ships binary files the
respective binary package will also be installed. That is, for a
package "foo", the package "foo.i386-linux" will also be installed on
an "i386-linux" system. This option suppresses this behavior, and also
implies "--no-depends". Don't use it unless you are sure of what you
Reinstall a package (including dependencies for collections) even if
it already seems to be installed (i.e, is present in the TLPDB). This
is useful to recover from accidental removal of files in the
When re-installing, only dependencies on normal packages are followed
(i.e., not those of category Scheme or Collection).
While not recommended, the "install-tl" program provides an option to
omit installation of all documentation and/or source files. (By
default, everything is installed.) After such an installation, you may
find that you want the documentation or source files for a given
package after all. You can get them by using these options in
conjunction with "--reinstall", as in (using the "fontspec" package as
tlmgr install --reinstall --with-doc --with-src fontspec
Thus if you have an installation without doc and src you can install it for a single package via
tlmgr install --reinstall --with-doc --with-src packagename
(my home PC has limited space, so I do the same if needed)
