Field names refer to fields on RawPackage and rawFile.
The file uses little endian encoding for the uint32s.
Strings are written into the string table at the end of the file.
Each string is prefixed with a uvarint-encoded length.
Bools are written as uint32s: 0 for false and 1 for true.

The following is the format for a full module:

“go index v2\n”
str uint32 - offset of string table
n uint32 - number of packages
