NAME

       opam-show - Display information about specific packages.

SYNOPSIS

       opam show [OPTION]... [PATTERNS]...

DESCRIPTION

       This command displays the information block for the selected package(s).

       The information block consists in the name of the package, the installed version if this package is
       installed in the currently selected compiler, the list of available (installable) versions, and a
       complete description.

       opam list can be used to display the list of available packages as well as a short description for each.

ARGUMENTS

       PATTERNS
           List of package patterns.
