| DepfileParser | Parser for the dependency information emitted by gcc's -M flags |
| DepfileParserTest | |
| DepsLog::Deps | |
| DepsLog | As build commands run they can output extra dependency information (e.g |
| DiskInterface | Interface for accessing the disk |
| Edge | An edge in the dependency graph; links between Nodes using Rules |

| ExternalStringHashMap< V > | A template for hash_maps keyed by a StringPiece whose string is owned externally (typically by the values) |
| FakeCommandRunner | Fake implementation of CommandRunner, useful for tests |
| ManifestParser::FileReader | |
| GETOPT_LONG_OPTION_T | |
| GraphTest | |
| GraphViz | Runs the process of creating GraphViz .dot file output |

| ImplicitDepLoader | ImplicitDepLoader loads implicit dependencies, as referenced via the "depfile" attribute in build files |
| IncludesNormalize | Utility functions for normalizing include paths on Windows |
| LaconicPrinter | A test result printer that's less wordy than gtest's default |

| ManifestParser | Parses .ninja files |
| Metric | The Metrics module is used for the debug mode that dumps timing stats of various actions |
| Metrics | The singleton that stores metrics and prints the report |
| Node | Information about a node in the dependency graph: the file, whether it's dirty, mtime, etc |
| ParserTest | |

| Subprocess | Subprocess wraps a single async subprocess |
| SubprocessSet | SubprocessSet runs a ppoll/pselect() loop around a set of Subprocesses |
| VirtualFileSystem | An implementation of DiskInterface that uses an in-memory representation of disk state |
