# This module enables a class to host capabilities. Prior to being able
|
||||
# to use any capabilities, the `initialize_capabilities!` method must be
|
||||
# called.
|
||||
#
|
||||
# Capabilities allow small pieces of functionality to be plugged in using
|
||||
# the Vagrant plugin model. Capabilities even allow for a certain amount
|
||||
# of inheritence, where only a subset of capabilities may be implemented but
|
||||
# a parent implements the rest.
|
||||
#
|
||||
# Capabilities are used heavily in Vagrant for host/guest interactions. For
|
||||
# example, "mount_nfs_folder" is a guest-OS specific operation, so capabilities
|
||||
# defer these operations to the guest.

||||

# we should auto-detect it.

# implements `#detect?` and value[1] is a parent host (if any).

|
