# Usage: ./deploy [app]; if app is missing, all apps under this directory will
# be deployed; otherwise deploy the app(s) specified. Note the shiny-dev-center
# repository must be under the same directory of this shiny-examples repository.
# Please ask garrett@rstudio.com if you want the credentials for the account
# `gallery` on ShinyApps.io. There are two optional arguments -d and -p, meaning
# deploy the app(s) without publishing to the gallery, and publish without
# deployment.
