# I tried to use the autoconf/automake/autolocal/etc (i.e. autohell) tools
# but I just couldn't stomach them. Since this is a Makefile for POSIX
# systems, I will simply do away with autohell completely and use a GNU
# Makefile. GNU make ought to be available pretty much everywhere, so I
# don't see this being a significant issue for portability.
# All commands assume a GNU compiler. For systems which do not use a GNU
# compiler, write scripts with the same names as these commands, and taking
# the same arguments, and translate the arguments and commands into the
# appropriate non-POSIX ones as needed. libs3 assumes a GNU toolchain as
# the most portable way to build software possible. Non-POSIX, non-GNU
# systems can do the work of supporting this build infrastructure.

# Determine verbosity. VERBOSE_SHOW should be prepended to every command which
# should only be displayed if VERBOSE is set. QUIET_ECHO may be used to
# echo text only if VERBOSE is not set. Typically, a VERBOSE_SHOW command will
# be paired with a QUIET_ECHO command, to provide a command which is displayed
# in VERBOSE mode, along with text which is displayed in non-VERBOSE mode to
# describe the command.
#
# No matter what VERBOSE is defined to, it ends up as true if it's defined.
# This will be weird if you defined VERBOSE=false in the environment, and we
# switch it to true here; but the meaning of VERBOSE is, "if it's defined to
# any value, then verbosity is turned on". So don't define VERBOSE if you
# don't want verbosity in the build process.
