#******************************************************************************
#
# ACPICA package generation script for Cygwin/Windows execution
#
# Requires cygwin be installed - http://www.cygwin.com
# and its /bin be *first* in your path.
#
# Windows packages require pkzip25 (free, and is available from numerous
# sources - search for "pkzip25" or "pkzip25.exe")
#
# Execute this script from the acpica/generate/release directory.
#
# Constructed packages are placed in the acpica/generate/release/current
# directory.
#
# Line Terminators: Windows source packages leave the CR/LF terminator.
# Unix packages convert the CR/LF terminators to LF only.
#
# Usage:
#
#   build <package_type> <target_type>
#
#   where:
#       <package_type> is one of:
#           source  - Build an ACPICA source package (core and all tools)
#           test    - Build an ACPICA test suite package
#           binary  - Build an ACPICA binary tools package
#
#       <target_type> is one of:
#           win     - Generate Windows package (Intel license, CRLF line terminators)
#           unix    - Generate Unix package (Intel license, LF line terminators)
#           unix2   - Generate Unix package (dual license, LF line terminators)
