Multiple Indexes

This release supports importing multiple indexes in parallel. Multiple indexes is important for the Bazel use case, where each Swift module generates its own index. Importing in parallel makes it much faster.

The release can be built against both Swift 5.0 and Swift 5.1.

The binary included with this release was built against swift-5.1-RELEASE

The README has also been improved since the last release.

Post V1

This release includes bug fixes and improves performance, including:

• Fixes handling of invalid regex (@ob #13)
• Works around llvm bug in replace_path_prefix (@ob #13)
• Use APFS file cloning (@kastiglione #15)

Also note that the initial version, 5.0.1.0, was incorrectly built against the master branch of clang-swift. This doesn't seem to be a problem in practice, the index APIs didn't change diverge. This release is properly built against Swift 5, specifically swift-5.0.1-RELEASE.

Initial release

This initial release supports supports Swift 5.0. Releases will be numbered $SWIFT_VERSION.$INDEX_IMPORT_VERSION, so this initial release is version 5.0.1.0.
