-// * Need to get proper version of crate when dealing with local dependencies
-//   Some crates are using '*' version for their local dependencies. DocBuilder
-//   or Crate must get proper version information. To do this, I am planning
-//   to find correct crate file in crates.io-index and generate a crate
-//   from it. And add a function like find_version to return correct version
