+Prerequisites
+-------------
+
+These are the prerequisites that the test library predefines with
+test_have_prereq.
+
+See the prereq argument to the test_* functions in the "Test harness
+library" section above and the "test_have_prereq" function for how to
+use these, and "test_set_prereq" for how to define your own.
+
+ - PERL & PYTHON
+
+   Git wasn't compiled with NO_PERL=YesPlease or
+   NO_PYTHON=YesPlease. Wrap any tests that need Perl or Python in
+   these.
+
+ - POSIXPERM
+
+   The filesystem supports POSIX style permission bits.
+
+ - BSLASHPSPEC
+
+   Backslashes in pathspec are not directory separators. This is not
+   set on Windows. See 6fd1106a for details.
+
+ - EXECKEEPSPID
+
+   The process retains the same pid across exec(2). See fb9a2bea for
+   details.
+
+ - SYMLINKS
+
+   The filesystem we're on supports symbolic links. E.g. a FAT
+   filesystem doesn't support these. See 704a3143 for details.
