-7 Generate a 7-bit scanner.

-8 Generate an 8-bit scanner (default).

-+ Generate a C++ scanner class.

-C Compress scanner tables but do not use equivalence classes.

-Ca

Align tables for memory access and computation. This creates

larger tables but gives faster performance.

-Ce

Construct equivalence classes. This creates smaller tables and

sacrifices little performance (default).

-Cf

Generate full scanner tables, not compressed.

-CF

Generate faster scanner tables, like -F.

-Cm

Construct metaequivalence classes (default).

-Cr

Bypass use of the standard I/O library; use read( ) system calls

instead.

fmt

fmt [options] [files]

Convert text to specified width by filling lines and removing

newlines. Concatenate files on the command line, or read text from

standard input if - (or no file) is specified. By default, preserve

blank lines, spacing, and indentation. fmt attempts to break lines at

the end of sentences and to avoid breaking lines after a sentence’s

first word or before its last.

Options

-c, --crown-margin

Crown margin mode. Do not change indentation of each para-

graph’s first two lines. Use the second line’s indentation as the

default for subsequent lines.

-p prefix, --prefix=prefix

Format only lines beginning with prefix.

-s, --split-only

Suppress line-joining.

-t, --tagged-paragraph ...
