# Builds an iOS module and places it in
# dist/ios/

# See build-tools/Env.sh for vars.sh requirement

# Usage:
#
# MODULE_MARKET_NAME="Human Friendly Name"
# MODULE_NAME="moduleName"
# MODULE_DESCRIPTION="The best module ever"
# MODULE_REPO_NAME="my-module"
#
# source build-tools/buildAndroidModule.sh
#
# MODULE_MARKET_NAME is simply used for some prints
# MODULE_NAME should be the name of the android module that needs to be built.
# MODULE_NAME does not support sub-modules. The module should be available
# at the root of the android project.
# MODULE_DESCRIPTION is the description used for pod specs.
# MODULE_REPO_NAME is the repository inside btfuse organization.

# It's assumed that:
#   - the ios workspace is located at in ./ios/
#   - it contains a VERSION file
#   - it contains a BUILD file
#   - That the workspace name and scheme have a consistent name
#   - That the repo has a LICENSE file
