Mandatory or optional arguments to long options are mandatory or optional for short options too.

Operation modes:

--help
display this help and exit
--version
output version information and exit
-E, --fatal-warnings
once: warnings become errors, twice: stop execution at first error
-i, --interactive
unbuffer output, ignore interrupts
-P, --prefix-builtins
force a `m4_' prefix to all builtins
-Q, --quiet, --silent
suppress some warnings for builtins
--warn-macro-sequence[=REGEXP]
warn if macro definition matches REGEXP, default \$\({[^}]*}\|[0-9][0-9]+\)

Preprocessor features:

-D, --define=NAME[=VALUE]
define NAME as having VALUE, or empty
-I, --include=DIRECTORY
append DIRECTORY to include path
-s, --synclines
generate `#line NUM "FILE"' lines
-U, --undefine=NAME
undefine NAME

Limits control:

-G, --traditional
suppress all GNU extensions
-H, --hashsize=PRIME
set symbol lookup hash table size [509]
-L, --nesting-limit=NUMBER
change artificial nesting limit [1024]

Frozen state files:

-F, --freeze-state=FILE
produce a frozen state on FILE at end
-R, --reload-state=FILE
reload a frozen state from FILE at start

Debugging:

-d, --debug[=FLAGS]
set debug level (no FLAGS implies `aeq')
--debugfile=FILE
redirect debug and trace output
-l, --arglength=NUM
restrict macro tracing size
-t, --trace=NAME
trace NAME when it is defined

FLAGS is any of:

a
show actual arguments
c
show before collect, after collect and after call
e
show expansion
f
say current input file name
i
show changes in input files
l
say current input line number
p
show results of path searches
q
quote values as necessary, with a or e flag
t
trace for all macro calls, not only traceon'ed
x
add a unique macro call id, useful with c flag
V
shorthand for all of the above flags

If defined, the environment variable `M4PATH' is a colon-separated list of directories included after any specified by `-I'.

Exit status is 0 for success, 1 for failure, 63 for frozen file version mismatch, or whatever value was passed to the m4exit macro.

Simplement parce que lors du lancement d'un programme DOS ou Windows
(fichier EXE-COM-BAT), MultideskOS met l'écran en mode texte, afin que
le chargement du programme Windows soit plus rapides. En effet, Windows,
lorsqu'il reprend la main sur MultideskOS, sauve son environement comme
pour tout autre programme, avant de le mettre en réduction dans la
barre. De ce fait, si votre MultideskOS tourne en 1024x768, Windows va
devoir sauver 786 432 pixels + tout le reste, ce qui prend 3 à 10
secondes suivant les machines alors que l'opération est immédiate
lorsque MultideskOS s'en occupe et met l'écran temporairement en mode
texte. Il vous suffira par la suite de presser simplement une touche
pour que votre bureau MultideskOS apparaisse comme avant.
