   special way:
   - Space and tab are interpreted as delimiters. They are not treated as
     delimiters if they are surrounded by double quotes: "...".
   - Unescaped double quotes are removed from the input. Their only effect is
     that within double quotes, space and tab are treated like normal
     characters.
   - Backslashes not followed by double quotes are not special.
   - But 2*n+1 backslashes followed by a double quote become
     n backslashes followed by a double quote (n >= 0):

# The TAGs below are defined such that we never get into a situation
# in which we disable both kinds of libraries.  Given conflicting
# choices, we go for a static library, that is the most portable,
# since we can't tell whether shared libraries were disabled because
# the user asked for that or because the platform doesn't support
# them.  This is particularly important on AIX, because we don't
# support having both static and shared libraries enabled at the same
# time on that platform, so we default to a shared-only configuration.
# If a disable-shared tag is given, we'll fallback to a static-only
# configuration.  But we'll never go from static-only to shared-only.

===== general format =====
HAVE_STRLEN			ac_test
HAVE_STRING_H			ac_header
HAVE_CAN_FSTACKPROTECTORALL	ac_flags

==== cpp definitions ====
DEBUG				dont use in production, wants gcc, implies:
DEBUG_LEAKS			enable freeing resources before exiting
MKSHRC_PATH			"~/.mkshrc" (do not change)
MKSH_A4PB			force use of arc4random_pushb
MKSH_ASSUME_UTF8		(0=disabled, 1=enabled; default: unset)
MKSH_BINSHPOSIX			if */sh or */-sh, enable set -o posix
MKSH_BINSHREDUCED		if */sh or */-sh, enable set -o sh
MKSH_CLRTOEOL_STRING		"\033[K"
MKSH_CLS_STRING			"\033[;H\033[J"

MKSH_DEFAULT_PROFILEDIR		"/etc" (do not change)
MKSH_DEFAULT_TMPDIR		"/tmp" (do not change)
MKSH_DISABLE_DEPRECATED		disable code paths scheduled for later removal
MKSH_DISABLE_EXPERIMENTAL	disable code not yet comfy for (LTS) snapshots
MKSH_DISABLE_TTY_WARNING	shut up warning about ctty if OS cant be fixed
MKSH_DONT_EMIT_IDSTRING		omit RCS IDs from binary
MKSH_MIDNIGHTBSD01ASH_COMPAT	set -o sh: additional compatibility quirk
MKSH_NOPROSPECTOFWORK		disable jobs, co-processes, etc. (do not use)
MKSH_NOPWNAM			skip PAM calls, for -static on glibc or Solaris
MKSH_NO_CMDLINE_EDITING		disable command line editing code entirely
MKSH_NO_DEPRECATED_WARNING	omit warning when deprecated stuff is run
MKSH_NO_LIMITS			omit ulimit code
MKSH_NO_SIGSETJMP		define if sigsetjmp is broken or not available
MKSH_NO_SIGSUSPEND		use sigprocmask+pause instead of sigsuspend
MKSH_SMALL			omit some code, optimise hard for size (slower)
MKSH_SMALL_BUT_FAST		disable some hard-for-size optim. (modern sys.)
MKSH_S_NOVI=1			disable Vi editing mode (default if MKSH_SMALL)
MKSH_TYPEDEF_SIG_ATOMIC_T	define to e.g. 'int' if sig_atomic_t is missing
MKSH_TYPEDEF_SSIZE_T		define to e.g. 'long' if your OS has no ssize_t
MKSH_UNEMPLOYED			disable job control (but not jobs/co-processes)

=== generic installation instructions ===

Set CC and possibly CFLAGS, CPPFLAGS, LDFLAGS, LIBS. If cross-compiling,
also set TARGET_OS. To disable tests, set e.g. HAVE_STRLCPY=0; to enable
them, set to a value other than 0 or 1. Ensure /bin/ed is installed. For
MKSH_SMALL but with Vi mode, add -DMKSH_S_NOVI=0 to CPPFLAGS as well.

Normally, the following command is what you want to run, then:
$ (sh Build.sh -r -c lto && ./test.sh -f) 2>&1 | tee log

Copy dot.mkshrc to /etc/skel/.mkshrc; install mksh into $prefix/bin; or
/bin; install the manpage, if omitting the -r flag a catmanpage is made
using $NROFF. Consider using a forward script as /etc/skel/.mkshrc like
http://anonscm.debian.org/cgit/collab-maint/mksh.git/plain/debian/.mkshrc
and put dot.mkshrc as /etc/mkshrc so users need not keep up their HOME.

You may also want to install the lksh binary (also as /bin/sh) built by:
$ CPPFLAGS="$CPPFLAGS -DMKSH_BINSHPOSIX" sh Build.sh -L -r -c lto

# Idea: I Want a flame graph based on determistic data!  That way you get the

# for thread_id, frame in sys._current_frames().items():
#   if thread_id == my_thread:
#     continue

# Note that opening file descriptors can cause bugs!  I have to open it above
# descriptor 10!

# python-flamegraph
# - suffers from measurement error due to threads.  
# - is RunCommandSub is being inflated?
#    - well actually i'm not sure.  I have to do it myself on a single thread
#    and see.
# pytracing:
# - the format is too bloated.  It can't handle abuild -h.  So I have to
# optimize it.
#
# I want to unify these two approaches: both flame graphs and function traces.
#
# Advantage: sys.setprofile() gets C function call events!
#
# Reservoir Sampling!  Get a list of all unique stacks.

# You can figure out the stack from the current/call/return sequence.  So you

## OSH Parser Performance

We time `$sh -n $file` for various files under various shells, and repeat then
run under cachegrind for stable metrics.

Lower numbers are generally better, but each shell recognizes a different
language, and OSH uses a more thorough parsing algorithm.  In **thousands** of
"I refs".
