+
+Any option argument is overwritten by the respective additional program
+argument. Options may be given in any order, and are also considered
+options if located after the first program argument. Too many program
+arguments are silently ignored.
+
+$extd-c$norm, $extd--compile$norm ${ital}FILE$norm | ${ital}DIRECTORY$norm
+ Compile subtitle text files according to subtitle index\
+ ${ital}FILE$norm
+ or to subtitle index files in ${ital}DIRECTORY$norm to\
+ ${ital}TARGET$norm. Clean up if this is successful, then exit.
+
+$extd-k$norm, $extd--keep$norm Keep subtitle stream file even if\
+ conversion is successful.
+
+$extd-l$norm, $extd--list$norm List subtitles for TITLE using\
+ ${extd}mplayer$norm(1) and exit.
+ If TITLE is not provided or \`$extd-$norm', list subtitles for
+ title #2 (as title #1 may be an intro without subtitles)
+ and exit.
+
+SOURCE Video DVD data source, i.e. a device (usually /dev/dvd),
+ a directory (e.g. one containing content created via
+ ${extd}dvdbackup$norm(1)) or a Video DVD image file.
+ If \`$extd-$norm', a previously created subtitle stream file\
+ named
+ ${extd}subtitle_stream-$norm*$extd-${norm}TITLE${extd}-${norm}SUBTITLE\
+ in the current working
+ directory will be used for only the stream-to-graphics-
+ to-text conversion instead. Both TITLE and SUBTITLE
+ must not be \`$extd-$norm' in that case.
+ The default is \`$extd/dev/dvd$norm'.
+
+$extd-t$norm, $extd--title$norm
+ TITLE Number of the title (1-n) which will be accessed for
+ subtitle stream extraction. If left out or \`$extd-$norm', the
+ program uses ${extd}mplayer$norm(1) to detect how many titles are
+ available on the DVD data source and asks for the
+ title to be accessed.
+
+$extd-s$norm, $extd--subtitle-id$norm
+ SUBTITLE ID of the subtitle stream to be extracted (0-n).
+ If left out or \`$extd-$norm', the program uses its\
+ ${extd}-l$norm option to detect
+ which subtitles are available for the given TITLE and asks
+ for the ID to be used.
+
+$extd-o$norm, $extd--output-target$norm
+ TARGET Name of the resulting subtitles text file.
+ If not provided, the file is named after the subtitle stream
+ file. NOTE: Unlike previous versions, this version appends
+ the filename suffix $extd.srt$norm automagically ONLY in that\
+ case.
+
+$extd-g$norm, $extd--grey-levels$norm
+ GREY_LEVELS Optional grey-levels value\
+ (\`c0$extd,${norm}c1$extd,${norm}c2$extd,${norm}c3' with 0 <= cN <= 255,
+ where 0 is black and 255 is white) to be used for converting
+ the subtitle stream graphics to text via OCR. The default is
+ \`${extd}255,255,0,255$norm'. Unfortunately, the\
+ ${extd}subtitle2pgm$norm program,
+ which requires this value, appears to be poorly documented;
+ if you find a more detailed, working documentation, please
+ refer to it and inform this program's author about it.
+
+$extd-h$norm, $extd--help$norm Display this help and exit.
+$extd-v$norm, $extd--verbose$norm Be verbose. The number of ${extd}-v$norm\
+ options specify the level of
+ verbosity.
+$extd-V$norm, $extd--version$norm Display version information and exit.
+
+${extd}EXIT STATUS$norm

+
+
+.SH DESCRIPTION
+
+Uses
+.BR tccat (1)
+and
+.BR tcextract (1)
+from the
+.B transcode
+package to extract a subtitle stream from DVD data. This stream is converted
+into image files with
+.BR subtitle2pgm ,
+and those are converted to text files using
+.BR pgm2txt ,
+both from the
+.B subtitleripper
+package, which in turn calls
+.BR gocr (1).
+.PP
+The previously created subtitle index file (.srtx) and the resulting text
+files are then compiled into one text file using either
+.BR srttool ,
+from the
+.B subtitleripper
+package, or
+.BR sed (1).
+(See Output Format below.)
+.PP
+The
+.B -c
+option allows for compiling existing text files into that format according
+a subtitle index file without extracting a subtitle stream first (see below).
+\" .PP
+\" If the
+\" .B -S
+\" option is used, this program also performs a minor correction of common
+\" misrecognition errors via
+\" .BR sed (1),
+\" i.e. a standalone `l' (small letter L) or one followed by an apostrophe
+\" is converted to `I' (capital letter I).
+.PP
+All temporary files are deleted afterwards (`clean-up'), unless a fatal error
+occurred or a user interrupt was detected; the extracted subtitle stream file
+is kept for future use if the
+.B -k
+option is used.
+.PP
+Based on
+.B DVD ripping and transcoding with Linux
+by Moritz Bunkus <moritz@bunkus.org>, available at
+.br
+<\fIhttp://www.bunkus.org/dvdripping4linux/\fP>.
+
+.SS Output Format
+The format of the subtitle text file this program creates is similar to that the
+.B SubRip
+program creates:
+.PP
+.I Subtitle number
+.br
+.IB "Start time " --> " End time"
+.br
+.I Text of subtitle (one or more lines)
+.br
+.I Blank line
+.PP
+Like the SubRip format, field data starts at the beginning of each line.
+The time format used is `\fIhours\fB:\fIminutes\fB:\fIseconds\fR',
+.I hours
+and
+.I minutes
+with two digits each. The
+.I seconds
+field is precise to three decimal points; the decimal separator used is
+the comma.
+.PP
+Different to the SubRip format, the line break used is the
+standard UNIX Line Feed (LF, 0x0A) character. The
+.I Subtitle number
+field was not included before version 0.6.1.
+
+
+.SH OPTIONS
+
+Options are supported since version 0.4. This aims at achieving POSIX
+conformance and easy introduction of new features while maintaining
+backwards compatibility to versions before 0.4.
+.PP
+If additional program arguments are used, any option argument is
+overwritten by the corresponding program argument. Options may be
+given in any order, and are also considered options if located after
+the first program argument. Too many program arguments are silently
+ignored.
+
+.IP "\fB-c\fP, \fB--compile\fP (\fIFILE\fP | \fIDIRECTORY\fP)"
+(since version 0.6.1, \fBTODO\fP) Compile one group, or all groups of
+subtitle text files in
+.IR DIRECTORY ,
+according to a corresponding subtitle index
+.I FILE
+(.srtx), into one text file each. If this is successful, clean up (see
+.BR -k )
+and exit.
+Options irrelevant to this process are ignored.
+
+.RS
+If a
+.I DIRECTORY
+is specified as argument, the
+.B -o
+option is ignored. The resulting text files are named after the
+corresponding subtitle index files found in the
+.I DIRECTORY
+instead, and their name is suffixed with `\fB.srt\fP'.
+.RE
+
+.IP "\fB-k\fP, \fB--keep\fP"
+(since version 0.6) Keep subtitle stream file even if conversion is successful.
+
+.IP "\fB-l\fP, \fB--list\fP"
+(since version 0.5) List subtitles for
+.I TITLE
+using
+.BR mplayer (1)
+and exit. If
+.I TITLE
+is not provided or
+.RB ` - ',
+list subtitles for title #2 (as title #1 may be an intro without subtitles) and
+exit.
+
+.IP "\fISOURCE\fP"
+Video DVD data source, i.e. a device
+.RI "(usually " /dev/dvd ),
+a directory e.g. one containing content created via
+.BR dvdbackup (1),
+or a Video DVD image file.
+.br
+If
+.RB ` - ',
+a previously created subtitle stream file named
+\fBsubtitle_stream-\fP*\fB-\fP\fITITLE\fP-\fISUBTITLE\fP
+in the current working directory will be used for only the
+stream-to-graphics-to-text conversion instead. Both
+.I TITLE
+and
+.I SUBTITLE
+must not be
+.BR ` - '
+in that case.
+.br
+The default is
+.RI ` /dev/dvd '.
+
+.IP "\fB-t\fP, \fB--title\fP \fITITLE\fP"
+Number of the title (1-n) which will be accessed for subtitle stream extraction.
+If omitted or
+.RB ` - ',
+the program uses
+.BR mplayer (1)
+to detect how many titles are available on the DVD data source and asks for the
+title to be accessed.
+
+.IP "\fB-s\fP, \fB--subtitle-id\fP \fISUBTITLE\fP"
+ID of the subtitle stream to be extracted (0-n). If omitted or
+.RB ` - ',
+the program uses its
+.B -l
+option (or
+.BR mplayer (1)
+directly, before version 0.5) to detect which subtitles are available for the
+given TITLE and asks for the ID to be used.
+
+.IP "\fB-o\fP, \fB--output-target\fP \fITARGET\fP"
+Name of the resulting subtitles text file. If not provided or
+.RB ` - ',
+the file is named after the subtitle stream file.
+
+.RS
+Versions prior to 0.6 appended the filename suffix
+.B .txt
+automagically always, and version 0.6 appended this suffix only if this option
+was not provided; since version 0.6.1, the filename suffix
+.B .srt
+(SubRip text) is appended in that case.
+
+.PP
+If the file already existed, behavior depends on the program version.
+
+.IP "Since version 0.6.1:"
+The program asks whether the file should be overwritten, new content should
+be appended to it (including a marker identifying the start of new content),
+or if a new file should be created. If the latter, the name of new file
+includes the ID of the
+.B dvdsubtitles
+process which created it.
+
+.IP "Version 0.6:"
+The program asks whether the file should be overwritten. If no, a new file
+is created, its name including the ID of the
+.B dvdsubtitles
+process which created it.
+
+.IP "Versions prior to 0.6:"
+New content is appended to the file without marker.
+.RE
+
+.IP "\fB-g\fP, \fB--grey-levels\fP \fIGREY_LEVELS\fP"
+Optional grey-levels value `\fIc0\fP,\fIc1\fP,\fIc2\fP,\fIc3\fP' with 0 <=
+.I cN
+<= 255, where 0 means black and 255 means white.
+
+.RS
+.PP
+DVD subtitles allow up to 4 colors. The comma-separated arguments to this
+option specify the grey level for each these colors that are used for converting
+the subtitle stream graphics into plain text via OCR. The default is
+.RB ` 255,255,0,255 '.
+The values
+.RB ` 255,0,255,255 ',
+.RB ` 255,255,255,0 ',
+and
+.RB ` 0,255,255,255 '
+can also produce viable OCR input.
+
+.PP
+Use solid (not outlined) shapes as input when possible to make things easier
+for the
+.BR gocr (1)
+program. It will ask you about a character if it does not recognize it; if
+that has an outlined shape, you are advised to cancel the OCR process (with
+Ctrl+C). This program will then allow you to use another grey-levels value
+without the need to extract the subtitle stream again.
+
+.PP
+See the README file of the
+.B subtitleripper
+package and of the
+.B subtitle2pgm
+program, which -c option requires this value, for details. (See FILES below.)
