release.sh

#
# Sourced (from the repository root) by mk.sh and mkdos.sh, which take their defaults from package.json:
#
#   "version"   the major and minor numbers (eg, 2.0 of "2.0.0") are the BASIC-DOS version, which this script copies to
#               VERSION_MAJOR (0-9) and VERSION_MINOR (0-99) in software/src/os/inc/version.inc whenever they change
#               (only then, since the makefiles depend on it); the minor number is displayed with two digits, so
#               "2.1.0" is BASIC-DOS 2.01, and "2.10.0" is 2.10
#   "config"    its "release" property ("final" or "debug") is the default build mode, which this script sets $release to
#               (in upper case); it's in "config" because VS Code's package.json schema expects a top-level "release"
#               property to be an object (semantic-release's configuration)

# setMode mode
#
# Records the build mode in tools/pc/disks/mkmode (which gulpfile.js also reads), and keeps each mode's build outputs
# (the OBJ folders, and tests/BIN) separately, so that switching modes doesn't rebuild everything: when the mode
# changes, each output folder is moved to tools/pc/disks/objs/<old mode>, and the new mode's folder is moved back from
# tools/pc/disks/objs/<new mode>, so MAKE sees that mode's last outputs (with their original timestamps) and rebuilds
# only what's changed since.  If the new mode has no saved folder yet, the old mode's outputs are copied instead (and
# left in place, so mk.sh can still boot them), and the folder's INCS file (which every module in the makefiles depends
# on) is deleted, so MAKE rebuilds everything in it (without touching any sources, which would make the other mode's
# saved outputs look out of date, too); if the last mode is unknown, its outputs aren't saved.
