// The mimemap-res.jar and mimemap-testing-res.jar genrules produce a .jar that
// has the resource file in a subdirectory res/ and testres/, respectively.
// They need to be in different paths because one of them ends up in a
// bootclasspath jar whereas the other one ends up in a test jar. Bootclasspath
// resources hide test or application resources under the same path because
// ClassLoader.getResource(String) consults the parent ClassLoader first.
//
// Further notes:
//  - the "cp" command will flatten any directory paths that occur in $(in),
//    but here they happen to already be in the root directory. If we needed
//    to preserve sub paths then we might want to zip the files first and then
//    unzip them below the new parent directory.
//  - the path names "res/" and "testres/" and duplicated in .java source files
//    (DefaultMimeMapFactory.java and MimeMapTest.java, as of October 2019).
