r"""Prints the lowest locally available SDK version greater than or equal to a
given minimum sdk version to standard output.
If --print_sdk_path is passed, then the script will also print the SDK path.
If --print_bin_path is passed, then the script will also print the path to the
toolchain bin dir.
Usage:
python find_sdk.py \
[--print_sdk_path] \
[--print_bin_path] \
10.6 # Ignores SDKs < 10.6
Sample Output:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/
10.14
