A simple way to only load the repos I want?

vimrc-vam.vim

" VAM for plugin management
" after setting this up
function! ActivateVAM()
    let addons_base = expand('$HOME') . '/vim-addons'
    let addons_manager = addons_base . '/vim-addon-manager'
    execute 'set runtimepath+=' . addons_manager

    if finddir(addons_base, '') == ''
        call mkdir(addons_base, '')
    endif
    if finddir(addons_manager) == ''
        execute 'cd ' . addons_base
        execute '!git clone git://github.com/MarcWeber/vim-addon-manager.git'
    endif
endfunction
