Constructor Summary
`DepsGenerator(Collection<SourceFile> deps, Collection<SourceFile> srcs, DepsGenerator.InclusionStrategy mergeStrategy, String closurePathAbs, ErrorManager errorManager)` Creates a new DepsGenerator.

Method Summary
`protected void`	`cleanUpDuplicatedFiles(Map<String,DependencyInfo> depsFiles, Map<String,DependencyInfo> jsFiles)` Removes duplicated depsInfo from jsFiles if this info already present in some of the parsed deps.js
`String`	`computeDependencyCalls()` Performs the parsing inputs and writing of outputs.
`protected DepsFileParser`	`createDepsFileParser()`
`protected String`	`formatPathToDepsFile(String path)` Format the deps file path so that it can be included in the output file.
