Usage: mfluajit [OPTION]... [MFNAME[.mf]] [COMMANDS] or: mfluajit [OPTION]... \FIRST-LINE or: mfluajit [OPTION]... &BASE ARGS Run MFLuaJIT on MFNAME, usually creating MFNAME.tfm and MFNAME.NNNNgf, where NNNN is the resolution of the specified mode (2602 by default). Any following COMMANDS are processed as Metafont input, after MFNAME is read. If the first line of MFNAME is %&BASE, and BASE is an existing .base file, use it. Else use `NAME.base', where NAME is the program invocation name, most commonly `mf'. Alternatively, if the first non-option argument begins with a backslash, interpret all non-option arguments as a line of Metafont input. Alternatively, if the first non-option argument begins with a &, the next word is taken as the BASE to read, overriding all else. Any remaining arguments are processed as above. If no arguments or options are specified, prompt for input. -base=BASENAME use BASENAME instead of program name or a %& line [-no]-file-line-error disable/enable file:line:error style messages -halt-on-error stop processing at the first error -ini be inimf, for dumping bases; this is implicitly true if the program name is `inimf' -interaction=STRING set interaction mode (STRING=batchmode/nonstopmode/ scrollmode/errorstopmode) -jobname=STRING set the job name to STRING -kpathsea-debug=NUMBER set path searching debugging flags according to the bits of NUMBER [-no]-mktex=FMT disable/enable mktexFMT generation (FMT=mflua) -output-directory=DIR use existing DIR as the directory to write files in [-no]-parse-first-line disable/enable parsing of first line of input file -progname=STRING set program (and base) name to STRING -recorder enable filename recorder -translate-file=TCXNAME use the TCX file TCXNAME -8bit make all characters printable by default -help display this help and exit -version output version information and exit Email bug reports to firstname.lastname@example.org.
