Interactive Prompts:
To complete these commands interactively, pass the --confirm (-c) flag to
the 'repository' command, or any of the inidivual subcommands.

The Default Repository:
The default repository is not stored on disk, but embedded in the binary and
can be used without explicitly specifying the name.  The default repository
is always listed first, and is assumed when creating a new function without
specifying a repository name prefix.
For example, to create a new Go function using the 'http' template from the
default repository.
	$ func create -l go -t http

The Repository Flag:
Installing repositories locally is optional.  To use a template from a remote
repository directly, it is possible to use the --repository flag on create.
This leaves the local disk untouched.  For example, To create a function using
the Boson Project Hello-World template without installing the template
repository locally, use the --repository (-r) flag on create:
	$ func create -l go \
		--template hello-world \
		--repository https://github.com/boson-project/templates

Alternative Repositories Location:
Repositories are stored on disk in ~/.config/func/repositories by default.
This location can be altered by setting the FUNC_REPOSITORIES_PATH
environment variable.

With no arguments, this help text is shown.  To manage repositories with
an interactive prompt, use the use the --confirm (-c) flag.
  $ func repository -c

add
  Add a new repository to the installed set.
    $ func repository add <name> <URL>

  For Example, to add the Boson Project repository:
    $ func repository add boson https://github.com/boson-project/templates

  Once added, a function can be created with templates from the new repository
  by prefixing the template name with the repository.  For example, to create
  a new function using the Go Hello World template:
    $ func create -l go -t boson/hello-world

list
  List all available repositories, including the installed default
  repository.  Repositories available are listed by name.  To see the URL
  which was used to install remotes, use --verbose (-v).

rename
  Rename a previously installed repository from <old> to <new>. Only installed
  repositories can be renamed.
    $ func repository rename <name> <new name>

remove
  Remove a repository by name.  Removes the repository from local storage
  entirely.  When in confirm mode (--confirm) it will confirm before
  deletion, but in regular mode this is done immediately, so please use
  caution, especially when using an altered repositories location
  (via the FUNC_REPOSITORIES_PATH environment variable).
    $ func repository remove <name>

o Add a repository and create a new function using a template from it:
  $ func repository add functastic https://github.com/knative-extensions/func-tastic
  $ func repository list
  default
  functastic
  $ func create -l go -t functastic/hello-world
  ...

	o Add a repository specifying the branch to use (metacontroller):
  $ func repository add metacontroller https://github.com/knative-extensions/func-tastic#metacontroler
  $ func repository list
  default
  metacontroller
  $ func create -l node -t metacontroller/metacontroller
  ...

o List all repositories including the URL from which remotes were installed
  $ func repository list -v
  default
  metacontroller	https://github.com/knative-extensions/func-tastic#metacontroller

o Rename an installed repository
  $ func repository list
  default
  boson
  $ func repository rename boson functastic
  $ func repository list
  default
  functastic

o Remove an installed repository
  $ func repository list
  default
  functastic
  $ func repository remove functastic
  $ func repository list
  default

func repository

  -c, --confirm   Prompt to confirm options interactively ($FUNC_CONFIRM)
  -h, --help      help for repository
  -v, --verbose   Print verbose logs ($FUNC_VERBOSE)
