    106 "This script is used to generate an NDK release package from scratch.
    107 
    108 This process is EXTREMELY LONG and consists in the following steps:
    109 
    110   - downloading toolchain sources from the Internet
    111   - patching them appropriately (if needed)
    112   - rebuilding the toolchain binaries for the host system
    113   - rebuilding the platforms and samples directories from ../development/ndk
    114   - packaging everything into a host-specific archive
    115 
    116 This can take several hours on a dual-core machine, even assuming a very
    117 nice Internet connection and plenty of RAM and disk space.
    118 
    119 Note that on Linux, if you have the 'mingw32' package installed, the script
    120 will also automatically generate a windows release package. You can prevent
    121 that by using the --platforms option.
    122 
    123 IMPORTANT:
    124         If you intend to package NDK releases often, please read the
    125         file named docs/DEVELOPMENT.TXT which provides ways to do that
    126         more quickly, by preparing toolchain binary tarballs that can be
    127         reused for each package operation. This will save you hours of
    128         your time compared to using this script!
