SVK::Command::Help - Show help

 help COMMAND

Optionally, svk help can pipe output through a pager, which is easier to read if the output is long. To use this feature, set the environmental variable SVKPAGER to some pager program.

For example:

    # bash, zsh users
    export SVKPAGER='/usr/bin/less'

    # tcsh users
    setenv SVKPAGER '/usr/bin/less'
