LexFromRawLexer - Lex a token from a designated raw lexer (one with no associated preprocessor object...
Encodes a location in the source.
This class handles loading and caching of source files into memory.
Token - This structure provides full information about a lexed token.
SourceLocation getLocation() const
Return a source location identifier for the specified offset in the current file.

isAtStartOfLine - Return true if this token is at the start of a line.
The JSON file list parser is used to communicate input to InstallAPI.
