# General rule for naming: variables with CAPITALIZED names hold settings,
# you can - and are expected - to modify it; variables with lowercase names

# Because most programs are written in FASM and have
# the common structure of one main .asm file possibly including
# several .inc files, we handle this case separately.
# Namely, we organize one big list of such programs
# (FASM_PROGRAMS, see below) containing name of local binary file,
# name of file inside kolibri.img and name of the source file.
# This list is maintained by hand, and the rest is done with some macroses...
# well, slightly complicated macroses - however, you do not need to
# understand them in order to maintain the list.
# To add a FASM program with one .asm file, just
# add the corresponding item to the list and enjoy
# the power of GNU make.

# The list of all FASM programs with one main FASM file.
# Every item consists of three parts, separated by ':'.
# First part is the real name of binary file in $(BUILD_DIR)
# as it should be produced by make.
# Second part is the name of a file inside kolibri.img,
# usually uppercased version of first part - to save space
# for FAT filesystem.
# Third part is the name of the source file.
# Spaces separate items, so spaces in names should be
# represented as '|'.

# twice, so they become $$$$.
