# This script takes the result of "make dist" and:
# 1) Unpacks it.
# 2) Ensures all contents are user-writable.  Some version control systems
#    keep code read-only until you explicitly ask to edit it, and the normal
#    "make dist" process does not correct for this, so the result is that
#    the entire dist is still marked read-only when unpacked, which is
#    annoying.  So, we fix it.
# 3) Convert MSVC project files to MSVC 2005, so that anyone who has version
#    2005 *or* 2008 can open them.  (In version control, we keep things in
#    MSVC 2008 format since that's what we use in development.)
# 4) Uses the result to create .tar.gz, .tar.bz2, and .zip versions and
#    deposites them in the "dist" directory.  In the .zip version, all
#    non-testdata .txt files are converted to Windows-style line endings.
# 5) Cleans up after itself.
