# SYNOPSIS
#
# Freestanding Hermetically-Sealed Monolithic Repository
#
# REQUIREMENTS
#
# You can run your programs on any operating system, but you have
# to build them on Linux 2.6+ (or WSL) using GNU Make. A modern C
# compiler that's statically-linked comes included as a courtesy.
#
# EXAMPLES
#
# # build and run everything
# make -j8 -O
# make -j8 -O MODE=dbg
# make -j8 -O MODE=opt
# make -j8 -O MODE=rel
# make -j8 -O MODE=tiny
#
# # build individual target
# make -j8 -O o//examples/hello.com
# o//examples/hello.com
#
# # view source
# less examples/hello.c
#
# # view binary
# o//tool/viz/bing.com o//examples/hello.com |
# o//tool/viz/fold.com
#
# # view transitive closure of legalese
# o//tool/viz/bing.com -n o//examples/hello.com |
# o//tool/viz/fold.com
#
# # basic debugging
# make -j8 -O MODE=dbg o/dbg/examples/crashreport.com
# o/dbg/examples/crashreport.com
# less examples/crashreport.c
#
# # extremely tiny binaries (scout's honor escape hatch)
# # please pay the $1k for commercial license if you can
# make -j8 -O MODE=tiny \
# LDFLAGS+=-s \
# CPPFLAGS+=-DIM_FEELING_NAUGHTY \
# CPPFLAGS+=-DSUPPORT_VECTOR=0b00000001 \
# o/tiny/examples/hello4.elf
# ls -hal o/tiny/examples/hello4.elf
# o/tiny/examples/hello4.elf
#
# TROUBLESHOOTING
#
# make -j8 -O SILENT=0 o//examples/hello.com

# UNSPECIFIED PREREQUISITES TUTORIAL
#
# A build rule must exist for all files that make needs to consider in
# order to build the requested goal. That includes input source files,
# even if the rule is empty and does nothing. Otherwise, the .DEFAULT
# rule gets triggered.
#
# This is a normal and neecssary behavior when source files get deleted.
# The build reacts automatically to this happening, by simply deleting
# and regenerating the dependency graph; so we can safely use wildcard.
#
# This is abnormal if it needs to keep doing that repeatedly. That can
# only mean the build config is broken.
#
# Also note that a suboptimal in-between state may exist, where running
# `make -pn` reveals rules being generated with the .DEFAULT target, but
# never get executed since they're not members of the transitive closure
# of `make all`. In that case the build config could be improved.
