=head1 NAME

B<findhyph> – find words hyphenated by TeX in a document

=head1 INSTALLATION

Copy B<findhyph> or B<findhyph.bat> (depending on OS used) to a directory 
included in system PATH. Perl interpreter is required to be in 
C</usr/bin/> for Unix-like systems or in PATH when using B<findhyph.bat>.

=head1 SYNOPSIS

B<findhyph [options]> F<foo.log>

=head1 DESCRIPTION

To use this program:

=over 4

=item 1)

set C<\tracingparagraphs=1> in a TeX document F<foo.tex> and run:

=item 2)

B<tex> F<foo.tex>

=item 3)

B<findhyph [options]> F<foo.log>

=back

If you are setting C<\looseness=E<lt>NE<gt>> to optimize paragraphs, 
you need to pass that information to the file F<foo.log> in a form 
C<@looseness=E<lt>NE<gt>> (on a separate line). You can use a macro like
C<\def\setlooseness#1{\looseness=#1 \immediate\write-1{@looseness=#1}}>
for this purpose. If the paragraph contains material in display math mode,
you need to use the macro in all split parts of the paragraph.

=head1 OPTIONS

=over 4

=item B<-c>

display hyphenated words in context

=item B<-f>

display font selectors and other strings starting with a backslash character

=item B<-v>

display program version

=item B<-p>

generate file containing information about one-letter prepositions and 
conjunctions left at the end of line

=item B<-l=STRING>

use prepositions/conjunctions listed in STRING instead of default list of 
prepositions and conjunctions C<kKsSvVzZoOuUiIA> used for Slovak and Czech
language

=back

=head1 OUTPUT FILES

=over 4

=item F<foo.hyph>

List of hyphenated words. All punctuation characters, parentheses and
other character immediately preceding or following displayed words are included
in this list. TeX constructs which are too difficult to display (C<\hbox{}>,
C<\mark{}> etc.) are shown as C<[]>. Math mode is indicated by C<$> sign.

Page numbers in square brackets refer to LOG file and may occasionally differ
from the typeset document. The reason is that TeX may need to break more 
paragraphs than it would eventually fit on the page in order to find a page
break.

Words hyphenated in footnotes are listed before the words hyphenated in the 
paragraph in which the footnote is referenced.

=item F<foo.prep>

List of prepositions if option B<-p> is used.

=head1 HISTORY

=head4 1.0 (2001-04-08)

=over 4

=item *

public release

=back

=head4 2.0 (2009-08-10)

=over 4

=item *

fixes in line breaks detection algorithm; support for the third pass of line
breaking algorithm in TeX (positive C<\emergencystretch>); support for 
discretionary breaks in the first pass

=item *

page number detection improved (recognized negative page numbers, compound page
numbers when C<\count1> to C<\count9> registers are non-zero
and C<[nn{mapfile}]>, C<[nnE<lt>pictureE<gt>]> and C<[nnE<lt>newlineE<gt>>
formats used by pdfTeX; false page number detection should be much more rare)

=item *

configurable list of prepositions and conjunctions

=item *

hyphenated words can be displayed in context

=item *

suggestions and testing by Pavel Stříž

=back

=head4 3.0 (2012-02-01)

=over 4

=item *

=item *

C<\looseness> setting is now taken into account (thanks to Karel Horák
for identifying the issue)
