invalid option -h
Usage: ampl [options] [file [file...]]
No file arguments means read from standard input, as does - by itself.
Options:
        -Cn {0 = suppress Cautions; 1 = default; 2 = treat as error;}*
        -Ln {0 = treat linear definitional constrs and var = decls as nonlin}*
        -P {skip presolve -- same as "option presolve 0;" }
        -S {substitute out definitional constraints (var = expression)}*
        -T {show genmod times for each item}*
        -enn {exit (if nn > 0) or abort command at |nn|-th error; 0 = no exit}*
        -f {do not treat unavailable functions of constant args as variable}*
        -g {run in a separate process group}
        -ix {import functions from x; specify -i? for details }
        -ooutopt {specify -o? for details}*
        -s[seed] {seed for random numbers; -s means current time}*
        -t {show times}*
        -v {show version and license details; -v? shows other -v options}
        --version {show version and exit, ignoring license files}
        -xnn {allow nn wall-clock seconds of execution time}
        -?? {show debug and obscure options}
* Equivalent option settings:
        -Cn     option Cautions n;              -Ln     option linelim n;
        -P      option presolve 0;              -S      option substout 1;
        -T      option gentimes 1;              -enn    option eexit nn;
        -f      option funcwarn 1;              -ofstub option outopt fstub;
        -s      option randseed '';             -snn    option randseed nn;
        -t      option times 1;
