;;; vlocitemacs.el --- Vlocity Build Tool :: Emacs integration

;;; Commentary:

;; Essentially the following commands are abstracted into elisp and made dynamic:

;; vlocity packDeploy -propertyfile build.properties -job job.yaml -key VlocityUITemplate/Test-test
;; vlocity packExport -propertyfile build.properties -job job.yaml -key VlocityUITemplate/Test-test
