NAME

6       reflow - Perl script for reflowing text files using Knuth's
7       paragraphing algorithm.

SYNOPSIS

10       reflow < input > output
11
12       reflow file1 file2 ... > output

DESCRIPTION

15       Uses Knuth's paragraphing algorithm (as used in TeX) to "reflow" text
16       files by picking "good" places to break the line.
17
18       It takes an ascii text file (with paragraphs separated by blank lines)
19       and reflows the paragraphs. If two or more lines in a row are
20       "indented" then they are assumed to be a quoted poem and are passed
21       through unchanged.  (The -skipindented causes ALL indented lines to be
22       passed unchanged)
23
24       The algorithm tries to keep the lines the same length but also tries to
25       break at punctuation, and avoid breaking within a proper name or after
26       certain "connectives" ("a", "the", etc.).
27
28   OPTIONS
29       -skipindented
30            Cause ALL indented lines to be passed unchanged. Normally a single
31            indented line is included in the paragraph, while two or more
32            indented lines are considered to be a quotation or poem and are
33            passed through unchanged.
34
35       -fast
36            Sets the optimum line width to 65 characters. This is the default.
37
38       -slow
39            Tries line widths of 60, 65 and 70 characters and picks the best
40            one.
41
42       -veryslow
43            Tries all line widths between 60 and 70 characters inclusive, and
44            picks the best one. With the -slow and -veryslow options the line
45            widths within a paragraph will vary less, but the line widths may
46            vary from one paragraph to the next.
47
48       -skipto pattern
49            Skip to the first line starting with the given pattern before
50            starting to reflow.  This is useful for skipping Project Gutenberg
51            headers or contents tables.
52
53            See Text::Reflow(3) for more options: all the keyword options
54            defined in Text::Reflow are also available via the reflow script.
