* byext.py
* byteyears.py
* cleanfuture.py
* copytime.py
* crlf.py
* db2pickle.py
* dutree.doc
* dutree.py
* find-uname.py
* find_recursionlimit.py
* finddiv.py
* findlinksto.py
* findnocoding.py
* fixcid.py
* fixdiv.py
* fixheader.py
* fixnotice.py
* fixps.py
* get-remote-certificate.py
* google.py
* highlight.py
* ifdef.py
* import_diagnostics.py
* lfcr.py
* linktree.py
* lll.py
* mailerdaemon.py
* make_ctype.py
* mkreal.py
* objgraph.py
* pdeps.py
* pickle2db.py
* pindent.py
* pysource.py
* reindent-rst.py
* rgrep.py
* suff.py

* which.py

Changes:

* Remove test_fixcid, test_lll, test_pdeps and test_pindent
  of test.test_tools.
* Remove get-remote-certificate.py changelog entry, since the script
  was removed.

Note: there is a copy of crlf.py in Lib/test/test_lib2to3/data/.
