# Note that the path could itself be a python file, or a directory

# Python's compile_all module only works on directories, and requires a max
# recursion depth

# Usage:
#    %py_byte_compile <interpereter> <path>
# Example:
#    %py_byte_compile %{__python3} %{buildroot}%{_datadir}/spam/plugins/

# This will terminate build on SyntaxErrors, if you want to avoid that,
# use it in a subshell like this:
#    (%{py_byte_compile <interpereter> <path>}) || :
