;;; govc.el --- Interface to govc for managing VMware ESXi and vCenter
;; Author: The govc developers
;; URL: https://github.com/vmware/govmomi/tree/main/govc/emacs
;; Keywords: convenience
;; Version: 0.31.0
;; Package-Requires: ((emacs "24.3") (dash "1.5.0") (s "1.9.0") (magit-popup "2.0.50") (json-mode "1.6.0"))
;; This file is NOT part of GNU Emacs.

;;; Commentary:
;; The goal of this package is to provide a simple interface for commonly used
;; govc commands within Emacs. This includes table based inventory/state modes
;; for vms, hosts, datastores and pools. The keymap for each mode provides
;; shortcuts for easily feeding the data in view to other govc commands.
;;
;; Within the various govc modes, press `?' to see a popup menu of options.
;; A menu bar is enabled for certain modes, such as `govc-vm-mode' and `govc-host-mode'.
;; There is also a `govc' menu at all times under the `Tools' menu.
;;
;; The recommended way to install govc.el is via MELPA (http://melpa.org/).

(setq govc-urls '(\"root:vagrant@localhost:18443#Vagrant-ESXi\"
\"root:password@192.168.1.192#Intel-NUC\"
\"Administrator@vsphere.local:password!@vcva-clovervm\"))
```
To enter a URL that is not in the list, prefix `universal-argument', for example:
`\\[universal-argument] \\[govc-vm]'
To avoid putting your credentials in a variable, you can use the
auth-source search integration.
```
(setq govc-urls '(\"myserver-vmware-2\"))
```
And then put this line in your `auth-sources' (e.g. `~/.authinfo.gpg'):
```
machine myserver-vmware-2 login tzz password mypass url \"myserver-vmware-2.some.domain.here:443?insecure=true\"
```
Which will result in the URL \"tzz:mypass@myserver-vmware-2.some.domain.here:443?insecure=true\".
For more details on `auth-sources', see Info node `(auth) Help for users'.
When in `govc-vm' or `govc-host' mode, a default URL is composed with the
