npm-docs(3) -- Docs for a package in a web browser maybe

SYNOPSIS

npm.commands.docs(package, callback)

DESCRIPTION

This command tries to guess at the likely location of a package's documentation URL, and then tries to open it using the --browser config param.

Like other commands, the first parameter is an array. This command only uses the first element, which is expected to be a package name with an optional version number.

This command will launch a browser, so this command may not be the most friendly for programmatic use.
