# Imports a text file containing symbol definitions, with a maximum of one symbol defined per line. Each symbol definition is in the form of "symbol_name address function_or_label", where "symbol_name" is the name of the symbol, "address" is the address of the symbol in one of the forms listed below, and "function_or_label" is either "f" or "l", with "f" indicating that a function is to be created and "l" indicating that a label is to be created.
# Address formats are the same as those that can be used with the "Go to address" function. For example:
# - 1234abcd
# - 0x1234abcd
# - ADDRESS_SPACE:1234abcd
# - ADDRESS_SPACE:0x1234abcd
# - MEMORY_REGION:1234abcd
# - MEMORY_REGION:0x1234abcd
# Omitting the address space or memory region specifier from the address will result in the function or label being created in the default address space.
