.SH DESCRIPTION
.PP
This command uses opam state to output information on how to use
installed libraries, updating the user's $PATH, and substitute variables
used in opam packages.
Apart from \f[I]opam config -env\f[], most of these commands are used by
opam internally, and thus are of limited interest for the user.
.SH OPTIONS
.TP
.B -env
Set the environment variables PATH, MANPATH, OCAML_TOPLEVEL_PATH and
CAML_LD_LIBRARY_PATH according to the current selected compiler.
The output of this command is meant to be evaluated by a shell, for
example by doing \f[I]eval \f[C]opam\ config\ -env\f[]\f[].
