"""Converts a .exports file to a format consumable by linkers.
|
|
|
|
An .exports file is a file with one exported symbol per line.
|
|
This script converts a .exports file into a format that linkers
|
|
can understand:
|
|
- It prepends a `_` to each line for use with -exported_symbols_list for Darwin
|
|
- It writes a .def file for use with /DEF: for Windows
|
|
- It writes a linker script for use with --version-script elsewhere
