# This file is used to build ninja itself, but it also serves as a
# documented example.
# The special variable "builddir" can be referenced later via the short
# name "@". The mnemonic comes from executables having an "@" prefix
# in ls -F output.
builddir = build
# Most other variables, like cflags, aren't magic at all; it's up to
# the rules to make use of them.
cflags = -g -Wall
# Here we declare a "rule" named "cxx", which knows how to compile
# C++ code. The variables indented below the rule are scoped to the
# rule itself. The "command" and "depfile" variables in rule scope
# are special; see the documentation.

# These build rules build the ".o" files from the ".cc" files,
# build "ninja.a" by linking the builddir's "ninja.o",
# and build that "ninja.o" by compiling "ninja.cc".
