$! notes  :
$! 1) lib_mysqludf_sys ( https://github.com/mysqludf/lib_mysqludf_sys ) is a "UDF" (User Designed
$!    Function) which will allow MySQL/MariaDB server to execute OS commands via UDF function
$!    'exec_sys'
$! 2) This script is a build command for OpenVMS-8.4 on Alpha or Itanium
$! 3) the initial compile will not work without the usual fiddling (about a dozen quick edits)
$!    with files located under MYSQL055_ROOT:[000000.include]
$!    CAVEAT: careful hackers will first copy all these files to a third directory where all the
$!    modifications will occur; it doesn't matter where they are located so long as you end up
$!    with a good compile and link
$! 4) Each UDF function requires three entries be present in the symbol table of the sharable
$!    image (called a 'shared object' in UNIX). So if you wanted to declare a new function called
$!    'yada' then you would also need 'yada_init' as well as 'yada_deinit'
$! 5) CAVEAT: be sure to check file protections; for some operations MySQL/MariaDB may need to
$!    run with additional privs
