%<Mmpfb%> creates a single-master PostScript Type 1 font by interpolating a\n\
multiple master font at a point you specify. The resulting font does not\n\

Usage: %s [OPTION]... FONT\n\
\n\
FONT is either the name of a PFA or PFB multiple master font file, or a\n\
PostScript font name. In the second case, mmpfb will find the actual outline\n\
file using the PSRESOURCEPATH environment variable.\n\
\n\
General options:\n\
--amcp-info Print AMCP info, if necessary, and exit.\n\
-a, --pfa Output PFA font.\n\
-b, --pfb Output PFB font. This is the default.\n\
-o, --output=FILE Write output to FILE.\n\
-p, --precision=N Set precision to N (larger means more precise).\n\
--subrs=N Limit output font to at most N subroutines.\n\
--no-minimize Do not replace original font%,s PostScript code.\n\
-h, --help Print this message and exit.\n\
-q, --quiet Do not generate any error messages.\n\
-v, --version Print version number and exit.\n\
\n\
Interpolation settings:\n\
-w, --weight=N Set weight to N.\n\
-W, --width=N Set width to N.\n\
-O, --optical-size=N Set optical size to N.\n\
--style=N Set style axis to N.\n\
