#the script 3builddistro has built it in sandbox3/build
#the quirky build will be in sandbox4.
#100912 changed name of quirky-kernel to 'kernel.qky', appended id-string. simplified puppy filenames.
#110422 DISTRO_VERSION variable now has dotted format. note, also now using full dotted version# in puppy filenames.
#121102 file DISTRO_SPECS has new variable DISTRO_DB_SUBNAME. ex: for 14.0-based slacko, DISTRO_DB_SUBNAME=slacko14
#130226 update.

#. ./DISTRO_SPECS
. ./sandbox3/rootfs-complete/etc/DISTRO_SPECS #100912 want DISTRO_IDSTRING, created by 3builddistro.
#...also has DISTRO_PUPPYSFS, DISTRO_ZDRVSFS, DISTRO_DEVXSFS simplified puppy filenames.
