Remove outdated example scripts of the Tools/scripts/ directory. A
copy can be found in the old-demos project:
https://github.com/gvanrossum/old-demos

Removed scripts (39):

* 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
* texi2html.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/.

-# Convert GNU texinfo files into HTML, one file per node.
-# Based on Texinfo 2.14.
-# Usage: texi2html [-d] [-d] [-c] inputfile outputdirectory
-# The input file must be a complete texinfo file, e.g. emacs.texi.
-# This creates many files (one per info node) in the output directory,
-# overwriting existing files of the same name.  All files created have
-# ".html" as their extension.
-
-
-# XXX To do:
-# - handle @comment*** correctly
-# - handle @xref {some words} correctly
-# - handle @ftable correctly (items aren't indexed?)
-# - handle @itemx properly
-# - handle @exdent properly
-# - add links directly to the proper line from indices
-# - check against the definitive list of @-cmds; we still miss (among others):
-# - @defindex (hard)
-# - @c(omment) in the middle of a line (rarely used)
-# - @this* (not really needed, only used in headers anyway)
-# - @today{} (ever used outside title page?)
-
-# More consistent handling of chapters/sections/etc.
-# Lots of documentation
-# Many more options:
-#       -top    designate top node
-#       -links  customize which types of links are included
-#       -split  split at chapters or sections instead of nodes
-#       -name   Allow different types of filename handling. Non unix systems
-#               will have problems with long node names
-#       ...
-# Support the most recent texinfo version and take a good look at HTML 3.0
-# More debugging output (customizable) and more flexible error handling
-# How about icons ?

-# rpyron 2002-05-07
-# Robert Pyron <rpyron@alum.mit.edu>
-# 1. BUGFIX: In function makefile(), strip blanks from the nodename.
-#    This is necessary to match the behavior of parser.makeref() and
-#    parser.do_node().
-# 2. BUGFIX fixed KeyError in end_ifset (well, I may have just made
-#    it go away, rather than fix it)
-# 3. BUGFIX allow @menu and menu items inside @ifset or @ifclear
-# 4. Support added for:
-#       @uref        URL reference
-#       @image       image file reference (see note below)
-#       @multitable  output an HTML table
-#       @vtable
-# 5. Partial support for accents, to match MAKEINFO output
-# 6. I added a new command-line option, '-H basename', to specify
-#    HTML Help output. This will cause three files to be created
-#    in the current directory:
-#       `basename`.hhp  HTML Help Workshop project file
-#       `basename`.hhc  Contents file for the project
-#       `basename`.hhk  Index file for the project
-#    When fed into HTML Help Workshop, the resulting file will be
-#    named `basename`.chm.
-# 7. A new class, HTMLHelp, to accomplish item 6.
-# 8. Various calls to HTMLHelp functions.
-# A NOTE ON IMAGES: Just as 'outputdirectory' must exist before
-# running this program, all referenced images must already exist
-# in outputdirectory.
