+0.1.4
+
+Replaced files-for-regexp, list-dir-re, list-dir-re-r, and filter-dirs with
+list-dir/files, list-files, and list-dirs.
+All three helpers support optional #:recursive #t traversal.
+Non-recursive results use complete paths so they can be passed directly to
+rm-f and rm-rf.
+Updated tests, examples, README, and Scribble documentation.
+
+0.1.3
+
+Added recursive and non-recursive regexp directory helpers:
+files-for-regexp, list-dir-re, list-dir-re-r, and filter-dirs.
+Added documentation and an example for regexp-based cleanup with rm-f/rm-rf.
+
 0.1.2
 
 Makefile loading no longer starts a build automatically.

+## Regexp-based cleanup
+
+For cleanup rules that need more control than globs, `racket-makefile` also
+provides small directory/regexp helpers. The results are ordinary path lists,
+so they can be passed directly to `rm-f` and `rm-rf` with `apply`:
+
+```racket
+#lang racket-makefile
+
+(default-target all)
+(phony all clean)

+(target all
+  (displayln "use (make clean)"))
+
+(target clean
+  (display "cleaning up...")

+  (apply rm-f
+         (list-files "." #px"(?i:(?:[.]bak|~)$)" #:recursive #t))
+  (displayln "done."))
+```
+
+`list-dir/files` returns matching files and directories. `list-files` and
+`list-dirs` restrict the result to files or directories. All three scan one
+directory level by default; use `#:recursive #t` to walk the complete tree.
+Non-recursive results are returned as complete paths, so the lists can be fed
+directly to `rm-f` or `rm-rf` with `apply`.
