+There are three methods to inhibit flymake in a file.  From most
+specific to most general, they are these:
+
+- `flymake-inhibit': a file-local-variable
+
+- `flymake-inhibit-buffer-name-regexps': a list of regexps to
+  match the buffer name against.  If one of them matches, inhibit
+  `flymake-mode'.
+
+- `flymake-inhibit-file-name-regexps': a list of regexps to match
+  the filename against.  If one of them matches, inhibit
+  `flymake-mode'.
+
+- `flymake-inhibit-major-modes': a list of major-modes in which
+  to inhibit `flymake-mode'.  Really only useful if you want to
+  generally add `flymake-mode' to `prog-mode-hook'."
