# Dumps all variables that match [A-Z][A-Z0-9_]* (with a few exceptions)

# to the file at $(1). It is used to print only the variables that are

# likely to be relevant to the product or board configuration.

# Soong config variables are dumped as $(call soong_config_set) calls

# instead of the raw variable values, because mk2rbc can't read the

# raw ones.
