+** Horizontal tabs
+Do not add horizontal tab characters to any file in Bison's repository
+except where required.  For example, do not use tabs to format C code.
+However, make files, ChangeLog, and some regular expressions require
+tabs.  Also, test cases might need to contain tabs to check that Bison
+properly processes tabs in its input.

+** TESTSUITEFLAGS
+
+The default is for make check to run all tests sequentially. This can be
+very time consumming when checking repeatedly or on slower setups. This can
+be sped up in two ways:
+
+Using -j, in a make-like fashion, for example:
+  $ make check TESTSUITEFLAGS='-j8'
+
+Running only the tests of a certain category, as specified in the AT files
+with AT_KEYWORDS([[category]]). Categories include:
+  - c++, for c++ parsers
+  - deprec, for tests concerning deprecated constructs.
+  - glr, for glr parsers
+  - java, for java parsers
+  - report, for automaton dumps
+
+To run a specific set of tests, use -k (for "keyword"). For example:
+  $ make check TESTSUITEFLAGS='-k c++'
+
+Both can be combined.
