SCons 1.1.0 released

Version 1.1.0 of SCons has been released and is now available at the
SCons download page:

    http://www.scons.org/download.php

This release notably contains significant memory utilization improvements,
Windows .rc file scanning, and TeX toolchain updates.

WHAT'S NEW IN THIS RELEASE

IMPORTANT: Python versions prior to 2.2 are supported by SCons 1.1.0,
but are officially deprecated and will generate a disableable warning
message. We plan to remove support for these older versions in SCons 2.0.
If removing this support would cause a problem for you, please contact
the dev@scons.tigris.org mailing list.

The following list summarizes the changes since the previous 1.0.1
minor release:

NEW FUNCTIONALITY

• A new --md5-chunksize option specifies the size of each block to
  read when calculating the MD5 checksum. Files smaller than the
  --md5-chunksize value (default 64 Kbytes) will be held in memory.
• New CheckCC, CheckCXX, CheckSHCC and CheckSHCXX tests have been added.
• SCons now scans Windows resource (.rc) files for implicit dependencies.
• SCons now supports $BIBINPUTS, $BSTINPUTS, $TEXINPUTS and $TEXPICTS
  search paths for various types of TeX input file.

CHANGED/ENHANCED EXISTING FUNCTIONALITY

• Visual C/C++ compilation command lines now put /Fo and the target
  object file name at the beginning of the command line.
• The scons wrapper script will now find the SCons library in a
  directory named "scons-local" (with no version number) if it exists.
• SCons now raises an AttributeError, not a KeyError, when a builder
  can not be found attached to a given construction environment.
• The add_src_builder() method can now be called to add a new
  source file builder to any builder object.
• The TeX builders now allow specification of a target name, instead
  of always using a default output name derived from the source.
• The TeX scanner now supports: glossaries, nomenclatures, lists of
  figures, lists of tables, hyperref and beamer.
• The PDFLaTeX scanner now searches for .gif files as well.
• The Glob() function now returns its matches in a fixed, sorted
  order, to prevent unnecessary rebuilds in subsequent invocations.
• The AppendENVPath() and PrependENVPath() methods now support a
  "delete_existing" keyword argument to removed duplicate entries.
• SCons now recognizes the .sx file suffix as an assembly language
  file that uses the C preprocessor.

FIXES

• Glob() no longer persists LIBPATH values across construction
  environments in certain situations.
• VariantDir now correctly duplicates #incude files in subdirectories.
• SCons now correctly finds the Python library directory even when
  it was installed in a directory that does not begin "python".
• Actions executed via the Execute() function now clear cached Node
  information.
• Error output when determining the gcc compiler version is now suppressed.
• SCons now correctly makes the subdirectory in which a SConsignFile()
  will be stored, if it doesn't already exist.
• The $SOURCE macro can now be used in the target string passed to a Builder.
• SCons now uses the correct environment PATH (and therefore the correct
  executable) when determining the GCC compiler version.
• SCons now Suppresses error output when checking the GCC compiler version.
• TeX builds with VariantDir(duplicate=0) have been fixed.
• The LaTeX scanner now searches for graphics files on the TEXINPUTS path.

IMPROVEMENTS

• SCons now computes MD5 checksum of large files without reading the
  entire file contents into memory at once.
• Memory usage has been reduced when a directory is used as a dependency
  of another Node, such as an Alias.
• Memory usage has been reduced when Null Executor objects are used.
• SCons now handles interrupts of the TeX tool chains more robustly.
• SCons now avoids object reference cycles from Python frame objects.
• The --profile= argument now uses the cProfile module (instead of
  the slower profile module) if it's available.
• The SCons.compat layer no longer must be imported separately in modules.

DOCUMENTATION CHANGES

• Fix typos and formatting bugs in the man page.
