#### CATEGORY=Build
### Manage build ResultStore configuration.  ResultStore is a service
### for publishing and sharing build and test results (not artifacts).
### Fuchsia's results can be found at go/fxbtx (ResultStore UI).

## usage:
##  fx resultstore status
##       Show if ResultStore uploading during fx build is enabled or disabled
##       across both global (checkout) and local (build directory) scopes.
##
##  fx resultstore enable [--local] [--ninja | --bazel]
##       Enable ResultStore uploading during fx build.
##       --local: Write to the current build directory instead of globally.
##       --ninja: Enable only for Ninja uploads.
##       --bazel: Enable only for Bazel uploads.
##       If neither --ninja nor --bazel is specified, both will be enabled (all).
##
##  fx resultstore disable [--local]
##       Disable ResultStore uploading during fx build.
##       --local: Disable for the current build directory instead of globally.
##
## ResultStore data will contain information about the users's environment,
## including $USER name, and working directory.
## ResultStore data however, is only visible internally to Googlers.
