-If you're looking for something to read, I suggest running ../test/partest

-Usage: partest [<options>] [<test> <test> ...]
-  <test>: a path to a test designator, typically a .scala file or a directory.
-          Examples: files/pos/test1.scala, files/res/bug785
-
-  Test categories:
-    --all          run all tests (default, unless no options given)
-    --pos          Compile files that are expected to build
-    --neg          Compile files that are expected to fail
-    --run          Test JVM backend
-    --jvm          Test JVM backend
-    --res          Run resident compiler scenarii
-    --buildmanager Run Build Manager scenarii
-    --scalacheck   Run Scalacheck tests
-    --script       Run script files
-    --shootout     Run shootout tests
-    --scalap       Run scalap tests
-
-  Test "smart" categories:
-    --grep         run all tests with a source file containing <expr>
-    --failed       run all tests which failed on the last run
-
-  Specifying paths and additional flags, ~ means repository root:
-    --rootdir      path from ~ to partest (default: test)
-    --builddir     path from ~ to test build (default: build/pack)
-    --srcdir       path from --rootdir to sources (default: files)
-    --javaopts     flags to java on all runs (overrides JAVA_OPTS)
-    --scalacopts   flags to scalac on all tests (overrides SCALAC_OPTS)
-    --pack         alias for --builddir build/pack
-    --quick        alias for --builddir build/quick
-
-  Options influencing output:
-    --trace        show the individual steps taken by each test
-    --show-diff    show diff between log and check file
-    --show-log     show log on failures
-    --dry-run      do not run tests, only show their traces.
-    --terse        be less verbose (almost silent except for failures)
-    --verbose      be more verbose (additive with --trace)
-    --debug        maximum debugging output
-    --ansi         print output in color
-
-  Other options:
-    --timeout      Timeout in seconds
-    --cleanup      delete all stale files and dirs before run
-    --nocleanup    do not delete any logfiles or object dirs
-    --stats        collect and print statistics about the tests
-    --validate     examine test filesystem for inconsistencies
-    --version      print version

-/** A class to compare IndexedSeqs of objects.  The result of comparison
-    is a list of <code>change</code> objects which form an
-    edit script.  The objects compared are traditionally lines
-    of text from two files.  Comparison options such as "ignore
-    whitespace" are implemented by modifying the <code>equals</code>
-    and <code>hashcode</code> methods for the objects compared.

-   Algorithmica Vol. 1 No. 2, 1986, p 251.
-<p>
-   This class outputs different results from GNU diff 1.15 on some
-   inputs.  Our results are actually better (smaller change list, smaller
-   total size of changes), but it would be nice to know why.  Perhaps
-   there is a memory overwrite bug in GNU diff 1.15.
