Comment:
The `custom:` speciefier indicates it is not SPDX. Use something along the lines of `custom:proprietary`.

The line wrap looks good, but maybe make it consistent. I.e., if you are going to split at (I think you did) 90 characters, split the next line at 90 characters too... keep all of the lines for that block the same length.

Eg:

```
	for item in DiscordPTB chrome_100_percent.pak chrome_200_percent.pak icudtl.dat libEGL.so \
	libGLESv2.so libffmpeg.so locales natives_blob.bin resources resources.pak snapshot_blob.bin swiftshader v8_context_snapshot.bin; do
```
to

```
	for item in DiscordPTB chrome_100_percent.pak chrome_200_percent.pak icudtl.dat libEGL.so \
	libGLESv2.so libffmpeg.so locales natives_blob.bin resources resources.pak snapshot_blob.bin \
        swiftshader v8_context_snapshot.bin; do
```
