described in the documentation.
What Is 'twander'?
==================
'twander' is a macro-programmable Filesystem Browser which runs on both
Unix-like systems as well as Win32 systems. It embraces the best ideas
of both similar GUI-driven programs (Konqueror, Windows Explorer) as
well as text-based interfaces (Midnight Commander, List, Sweep).
Or, If You Prefer The "Elevator Pitch"
======================================
'twander' is:
- A better file browser for Unix and Win32. (Tested on FreeBSD, Linux, Win32.)
- A way to make browsing the same on all the OSs you use.
- A macro-programmable tool that lets *you* define the features.
- A GUI navigation front-end for your shell.
- A way to "can" workflows for your technically-challenged colleagues.
- A way to free yourself from the shackles of the mouse.
- A way to significantly speed up your day-to-day workflow.
- A Python/Tkinter application - about 3100/1300 lines of code/comments
- A RCT (Really Cool Tool) that will have you addicted in a day or two
See the web page for more information and a screen shot. Better still,
download the tarball and read the documentation.

Subject: ANN: SCons 0.95 supports Visual Studio 2003, Borland tools, "D"
SCons is a software construction tool (build tool, or make tool) written
in Python. It is based on the design which won the Software Carpentry
build tool competition in August 2000.
Version 0.95 of SCons has been released and is available for download
from the SCons web site:
http://www.scons.org/
Or through the download link at the SCons project page at SourceForge:
http://sourceforge.net/projects/scons/
RPM and Debian packages and a Win32 installer are all available, in
addition to the traditional .tar.gz and .zip files.
WHAT'S NEW IN THIS RELEASE?
IMPORTANT: Release 0.95 contains the following interface changes:
- The default behavior of the Zip() Builder is now to create a
compressed file.
- The "overrides" keyword argument when creating a Builder() has been
deprecated in favor of specifying the values directly with keyword
arguments.
- The meaning of the "mode" keyword argument values to the
SCons.Util.scons_subst() and SCons.Util.scons_subst_list() functions
have been changed. (These are internal functions and should have
no external effect, but we list them here for completeness.)
See the release notes for more information about these changes.
This release adds the following features:
- Microsoft Visual Studio 2003 (version 7.1) is now supported.
- The bcc32, ilink32 and tlib Borland tools are now supported.
- The Digital Mars "D" programming language is now supported.
- A new $MSVS_USE_MFC_DIRS construction variable controls whether the
Microsoft Visual Studio ATL and MFC directories are included in the
default INCLUDE and LIB paths.
- New AppendUnique() and PrependUnique() Environment methods add values
(flags) to construction variables only if they're not already present.
- New "rsrcpath" and "rsrcdir" attributes to the $TARGET, $TARGETS,
$SOURCE and $SOURCES construction variables allow Builder commands
to access Repository source directories when using a Builder.
- A new --debug=count option displays the numbers of various types
of internal objects created, when run under Python 2.1 or later.
- A new --debug=objects option dumps information about SCons internal
objects when run under Python 2.1 or later.
- A new --debug=memory option displays memory usage statistics when
run under Linux systems.
- A new ZIPCOMPRESSION construction variable controls whether the
internal Python action for the Zip Builder compresses the file
or not. The default value is zipfile.ZIP_DEFLATED, which generates
a compressed file.
- A new "toolpath" Tool() and Environment keyword allows Tool modules
to be searched for in specified local directories.
The following bug fixes have been added:
- SCons now gracefully handles non-string construction variables in
all known situations.
- Construction variables may now be recursively expanded (e.g. CCFLAGS =
"$CCFLAGS -g") without going into an infinite loop.
- Compile the moc_*.cc Qt files using the correct environment flags,
not those from the environment that first had Qt Builders attached.
- Expansions like ${TARGET.dir} now work properly in *PATH construction
variables (like CPPPATH, F77PATH, etc.).
- Qt support now works from a copied construction environment.
- The M4 Builder now changes correctly to a Repository directory when
the source file is in the source directory of a BuildDir.
- Automatic checkout of implicit dependency files from SCCS and RCS
has been fixed.
- Builder-specific override values are now always used in substitutions,
not just when there isn't a target-specific environment.
- SCons now properly checks for whether all of the objects going into
a SharedLibrary() are shared, even if the object was already built.
- SCons now correctly looks up a Win32 drive letter with no path ('C:')
as a directory.
- Specifying .class files as input to JavaH with the .class suffix
when they weren't generated using the Java Builder has been fixed.
- The env.Action() method now returns the correct type of
Action for its argument(s).
- The Configure() function now works when called from nested subsidiary
SConscript files more than one level deep.
- Error message spellings have been corrected from "non-existant" to
"non-existent."
- The EnsureSConsVersion() function now checks against the SCons
version, not the Python version, for all Python version.
- SCons now properly handles command-line arguments with multiple =
in them.
- SCons now correctly retrieves all files from cache when multiple
files would ordinarily be built by in a single Action.
- Use of a custom _concat() function in the construction environment
when calling _stripixes() has been fixed.
- The Fortran scanner is now case-insensitive for the INCLUDE string
(per the Fortan spec).
- Side-effect targets are now properly removed before building their
corresponding target.
- BuildDir() can, once again, be called multiple times with the same
target and source directory arguments.
- Output lines now stay (more nearly) together when -j is used.
- A bug in saving and restoring PackageOptions to a file has been fixed.
- Microsoft Visual Studio type libraries are now built in the target
directory, not the source directory.
- Generated Microsoft Visual Studio project files now re-invoke SCons
correctly regardless of whether the file was built via scons.bat
or scons.py.
- Evaluate $MSVSPROJECTSUFFIX and $MSVSSOLUTIONSUFFIX when the Builder
is invoked, not when the tool is initialized.
- A typo has been fixed in the Microsoft Visual C registry lookup
("VCComponents.dat", not "VSComponents.dat").
- When using Microsoft Visual C++, SCons now uses independently
configured "include," "lib" or "path" from the registry. Previously,
SCons would only use the values if all three were set in the registry.
- SCons now ignore any "6.1" version of Microsoft Visual C++ found in
the registry; this is apparently a phony version number (created by
later service packs?) that throws off the logic if the user had any
non-default paths configured.
- SCons now uses the Microsoft Visual C++ 6.0 paths by default if the
"msvc" Tool is specified but no version of MSVC is detected on disk.
The following miscellaneous improvements have been added:
- All *FLAGS variables now "do the right thing" (as much as possible)
when appending flags with either strings or lists of flags.
- The -H help text now lists the legal --debug values.
- SCons now supplies an error message if you try to configure a BuildDir
for a directory that already has one.
- The error message when a source file can't be found has been reworded
to make it more clear.
- SCons now supplies a useful error message, not a stack trace, if a
construction variable expansion contains a syntax error.
- SCons now supplies meaningful error messages, not stack traces, if
a non-Node is added as a source, dependency, or ignored dependency
of a Node.
- The $LIBS construction variable can now contain File nodes, and
can now be a single string or File node, not a list, when only one
library is needed.
- When scanning for libraries to link with, SCons no longer appends
$LIBPREFIXES or $LIBSUFFIXES values to the $LIBS values if they're
already present.
- SCons now allows a target that can have its Builder called multiple
times to be called through multiple environments without error,
so long as the Builder calls all use the same action.
- The message about ignoring a missing SConscript file is now a
suppressable Warning, not a hard-coded sys.stderr.write().
- On POSIX systems with the "env" command, spawn commands with the
more portable "env -" idiom, instead of "env -i".
- Improve Cygwin support by accomodating Cygwin Python's delusion that
it's running on a case-sensitive file system.
- Microsoft Visual Studio .NET and Visual C 6.0/7.0 path detection
has been updated and made more robust.
Memory utilization has been improved as follows:
- "Build" construction environments with overrides are now only
generated as needed, not for every target.
- Nodes now delete their build environments after they've been built.
The documentation has been improved:
- The User's Guide now has an appendix describing how to accomplish
various common tasks in Python.
- Mention of the still-unimplemented -e option has been removed.
- A man page typo of "JAVACHDIR" instead of "JARCHDIR" has been fixed.
- An undocumented "for_signature" argument in the __call__() example
of the "Variable Substitution" section has now been documented.
- An odd double-quote escape sequence in the man page has been fixed.
- The dbm_module argument to the SConsignFile() function has been
documented.
ABOUT SCONS
Distinctive features of SCons include:
- a global view of all dependencies; no multiple passes to get
everything built properly
- configuration files are Python scripts, allowing the full use of a
real scripting language to solve difficult build problems
- a modular architecture allows the SCons Build Engine to be
embedded in other Python software
- the ability to scan files for implicit dependencies (#include files);
- improved parallel build (-j) support that provides consistent
build speedup regardless of source tree layout
- use of MD5 signatures to decide if a file has really changed; no
need to "touch" files to fool make that something is up-to-date
- easily extensible through user-defined Builder and Scanner objects
- build actions can be Python code, as well as external commands
An scons-users mailing list is available for those interested in getting
started using SCons. You can subscribe at:
http://lists.sourceforge.net/lists/listinfo/scons-users
Alternatively, we invite you to subscribe to the low-volume
scons-announce mailing list to receive notification when new versions of
SCons become available:

Subject: http-fetcher 1.1.0 released!
Date: Thu, 11 Mar 2004 23:02:17 CST
Announcing the release of http-fetcher 1.1.0! This version adds support
for transparently following HTTP redirects, as well as some small
cleanup and compatibility improvements.
Download from the home page at:
http://http-fetcher.sourceforge.net/downloads.html
SourceForge project page: http://sourceforge.net/projects/http-fetcher/
Blurb:
http-fetcher is a small, robust, flexible library for downloading
files via HTTP using the GET method. It's easy to use, but it also
allows you to customize and manipulate your file requests through
altering the User Agent, Referer, timeout, etc. The error reporting
functions give you a simple, clean interface through which to obtain
information about a problem.
There are other libraries that handle HTTP requests, but are generally
more complex to use and are focused on different goals. http-fetcher is
designed to let you retrieve files via HTTP quickly and easily without
having to reinvent the wheel. From this base you can build interactive
download tools (like lfetch), site mirroring tools, web spiders,
anything with a need to do HTTP GETs.
ChangeLog:
1.1.0 - March 8, 2004
* Added the ability to transparently follow HTTP redirects,
configurable with the new http_setRedirects() function.
* Replaced direct reference to sys_errlist with a call to
strerror, which allows the library to build on NetBSD.
* Changed configure.in to configure.ac. Autoconf seems to be
happier.
* Made the html docs a little less ugly.
1.0.3 - October 14, 2003
* Added support for ports other than 80
* HTTP control structures use RFC 1945 compliant linebreaks
* Fixed bug where server response values with leading 0's were
read as octal
* Fixed error in timeout logic that prevented connections from
actually timing out
* Fixed possible realloc() related memory leak
* Data is now NULL terminated for safety
1.0.2 - April 22, 2003
* Fixed a buffer overflow (reported to BugTraq, see
http://www.securityfocus.com/bid/6531/info/) and a memory leak.
* Check for hstrerror and provide workaround if not present.
* Portability improvements, build process checks for necessary
functions.
* Includes specfile for building rpm packages.
* Includes http-fetcher.m4 macro file for inclusion with autoconf
1.0.1 - July 30, 2001
* Requests now include a "Host:" field to satisfy servers running
virtual domains (who would otherwise return a 404). Thanks for
the help, zealot!
* Libtool/project versioning also sorted out.
1.0.0 - July 4, 2001
* Initial release.
