NAME

       opam-list - Display the list of available packages.

SYNOPSIS

       opam list [OPTION]... [PATTERNS]...

DESCRIPTION

       This command displays the list of installed packages, or the list of all the available packages if the
       --all flag is used.

       Unless the --short switch is used, the output format displays one package per line, and each line
       contains the name of the package, the installed version or -- if the package is not installed, and a
       short description. In color mode, root packages (eg. manually installed) are underlined.

       The full description can be obtained by doing opam info <package>. You can search through the package
       descriptions using the opam search command.
