# ELKS System Builder
# This build script is also called in main.yml for GitHub Continuous Integration
#
# Usage: ./build.sh [auto [[ext] [[[allimages]]]]]
#   <no args>:  user build: build cross-compiler, menuconfig kernel and standard apps
#   auto        github CI build:: just IBM PC, 8018X, NECV25 kernel and standard apps
#   ext         also build external apps (requires OpenWatcom C installed)
#   allimages   also build all floppy and HD disk images
#
# After building the system once, the following can be used to rebuild the system:
#   $ make clean
#   $ make
#   $ ./buildext.sh all     # optionally build specified external apps (OpenWatcom reqd)
#   $ ./qemu.sh
#
