#
#  This is a script to create a TAR or ZIP binary distribution out of a
#  built source tree. The output file will be put at the top level of
#  the source tree, as "mysql-<vsn>....{tar.gz,zip}"
#
#  Note that the structure created by this script is slightly different from
#  what a normal "make install" would produce. No extra "mysql" sub directory
#  will be created, i.e. no "$prefix/include/mysql", "$prefix/lib/mysql" or
#  "$prefix/share/mysql".  This is because the build system explicitly calls
#  make with pkgdatadir=<datadir>, etc.
#
#  In GNU make/automake terms
#
#    "pkglibdir"     is set to the same as "libdir"
#    "pkgincludedir" is set to the same as "includedir"
#    "pkgdatadir"    is set to the same as "datadir"
#    "pkgplugindir"  is set to "$pkglibdir/plugin"
#    "pkgsuppdir"    is set to "@prefix@/support-files",
#                    normally the same as "datadir"
#
#  The temporary directory path given to "--tmp=<path>" has to be
#  absolute and with no spaces.
#
#  Note that for best result, the original "make" should be done with
#  the same arguments as used for "make install" below, especially the
#  'pkglibdir', as the RPATH should to be set correctly.
