+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+fIcy is a small icecast/shoutcast stream grabber suite for use under shell
+environment. Its goal is to automatically rip a stream into user customisable
+files. It will work with \s-1ICY\s0 compatible streams, allowing you to either to save
+the stream to disk or to pipe the output to a media player, or even both. fIcy,
+among other uses, is ideal for batch/unattended recording of radio programs and
+stream debugging.
+.PP
+The fIcy package includes:
+.IP "\-" 4
+fIcy itself, a stream separator/multiplexer,
+.IP "\-" 4
+fResync, a fast MPEG-resyncing utility,
+.IP "\-" 4
+fPls, a playlist frontend for fIcy.

+\& \-d Do not dump the output to stdout.
+\& Useful when only ripping.
+\&
+\& \-E num Enumerate files when song title [metadata] changes, starting at
+\& num. When 0, fIcy will try to find the highest unused file
+\& number automatically. Uses \-o as a prefix.
+\&
+\& \-h Help
+\&
+\& \-c Do not clobber files.
+\&
+\& \-m Use song title [metadata] when naming files. Uses \-o as prefix.
+\&
+\& \-n If the file exists create new one with .n as suffix.
+\&
+\& \-p When dumping to stdout consider writing errors as transient
+\& (that is: flush the output buffer until stdout is ready).
+\& Useful when you pipe the output to a media player and want to
+\& kill it while not interrupting the rip.
+\&
+\& \-o file Dump the output to file or use file as a prefix (depending on
+\& other settings). Hint: to dump without a prefix use "./".
+\&
+\& \-s suffix Use sfx as a suffix for new files.
+\& Hint: the .mp3/.m4a extension is NOT implicit.
+\&
+\& \-t Display song title [metadata] while ripping.
+\&
+\& \-r Remove/don\*(Aqt save partial chunks. This will skip the first
+\& chunk and remove the last one upon termination which are
+\& (supposedly) incomplete. To use in combination with \-m or \-E.
+\&
+\& \-q file Append "file name" sequence to file. The file name is written
+\& upon file completition. This may be used to trigger events and
+\& rejoin splitted parts with an external tool without \-E.
+\& fResync will use this file in the future.
+\&
+\& \-x regex Save only files whose title (NOT filename) matches against this
+\& (or one of these) extended regular expressions. Multiple \-x can
+\& be specified on the command line to form OR conditions. Dump
+\& unaffected. Can be combined with \-X.
+\&
+\& \-X regex Do NOT save files whose title matches against this extended
+\& regular expression. Same semantics as \-x.
+\&
+\& \-I file Load include/exclude REs from file. Each line must be prefixed
+\& with + or \- to indicate whether it\*(Aqs a positive or negative
+\& expression (\-xX).
+\&
+\& \-f expr Filter titles through the specified coprocessor expression. The
+\& raw title is passed to the expression (doesn\*(Aqt include any
+\& additional prefixes/suffixes). As the result will be used
+\& internally, some limitations apply. Read carefully the
+\& Filtering_ section.
+\&
+\& \-F file Filter titles through the specified coprocessor script. Same
+\& semantics as \-f, but the expressions are loaded from a file
+\& instead. Conflicts with \-f.
+\&
+\& \-C path Specify the path of the external title rewriting coprocessor.
+\& Defaults to "sed". The executable must support the \*(Aq\-e\*(Aq, \*(Aq\-f\*(Aq
+\& flags and operate through stdin/out, like "sed".
+\&
+\& \-M time Maximum recording time. See Notes_.
+\&
+\& \-i time Maximum network idle time. Stops recording after the specified
+\& amount of time is passed without network activity. Defaults to
+\& 0 (default tcp timeout).
+\&
+\& \-a file Read authentication credentials from file (the file must
+\& contain a line of the form user:password). Note that only the
+\& Basic HTTP authentication scheme is supported.
+\&
+\& \-l num Redirect follow limit. Defaults to 1. 0 disables redirection
+\& entirely.

+\& \-b By default fResync maps the entire file into memory when
+\& operating. However this can create problems on loaded systems
+\& with large files or when simulating. This reverts to a
+\& buffered I/O mode. This flag is also implicit when simulating.
+\&
+\& \-s Simulate the process. Print on the standard output the starting
+\& sync offset and stream length, but don\*(Aqt modify the source
+\& file.
+\&
+\& \-v Verbose.
+\&
+\& \-n frames Require/decode at least n valid consecutive frames to validate
+\& the sync offset. Defaults to 6.

+\& to determine the maximal region of the file to be checked.

+\&
+\& \-T time Wait time to pause after each failure.

+\& playlist via http. Forwarded to fIcy.
+\&
+\& \-a file Read authentication credentials from file. Same as fIcy\*(Aqs when
+\& loading a playlist via http. The credentials are automatically
+\& forwarded to fIcy, but you can override them when needed.
+\&
+\& \-l num Redirect follow limit. Same as fIcy\*(Aqs when loading a playlist
+\& via http. Forwarded to fIcy.
+\&
+\& \-d file Run as a daemon, redirecting messages to file. fIcy\*(Aqs \-d

+Cleanup a ripped and/or damaged mp3 file::
+.PP
+.Vb 1
+\& fResync file.mp3
+.Ve
+.SH "NOTES"
+.IX Header "NOTES"
+The output files produced by fIcy may miss audio framing information and
+headers since the separation does not consider the audio data. For this reason,
+your player 'may' (but should not) fail to reproduce the dump or output some
+initial noise: this is expected. fResync can be used to cleanup \s-1MPEG\s0 files
+after processing.
+.PP
+You can also use other tools such as mpgedit for cutting the file in arbitrary
+positions without diminishing the quality. Assuming that your song spans across
+three files (use \-q to know which ones), that's how to proceed::
+.PP
+.Vb 1
+\& cat 1.mp3 2.mp3 3.mp3 > temp.mp3 && xmpgedit temp.mp3
+.Ve
+.PP
+Do *not* resync the files if you're going to post-process them this way:
+fResync would remove at least one boundary frame on each file, while other
+tools could also insert extra empty frames to silence the decoder!
+.PP
+The \-M flag supported by both fIcy and fPls accepts a time specification in
+seconds, `HH:MM` or `N minutes/hours/days`. Time starts just after the
+connection has been established, but without counting further delays. Also
+beware that \-M specified in fPls means `cumulative recording time` (time
+accumulates across retries/timeouts), while \-M specified in fIcy means `single
+stream recording time` (recording stops at the first error or when the
+specified time has elapsed).
+.SH "FILTERING"
+.IX Header "FILTERING"
+Most online radio stations tend to put banners in the title that will be shown
+in the player, and eventually result in the filename. To overcome to this (and
+more), fIcy offers the possibility to rewrite each title through a normal sed
+script via the \*(L"\-fF\*(R" flags. A real sed coprocess is used along the execution so
+all of sed's power is available, but some limitations apply:
+.PP
+* Each line of input should result in one output line, and \s-1ONE\s0 \s-1ONLY\s0.
+.PP
+* Two consecutive identical titles will result in the second one
+ being ignored (thus \s-1NOT\s0 splitting the stream). Consider this rule,
+ as removing carefully the banner could result in a better separation.
+.PP
+* The resulting title will still apply for \-xXI as usual.
+.PP
+* Please note that the *title* is filtered, not the filename (which may
+ still have some characters removed/modified). Use \-tv to see what is
+ actually sent to the filter.
+.PP
+You can actually use any executable that works as a stream editor by specifying
+the path with '\-C'. The executable must support the '\-e' (inline expression)
+and '\-f' (script file) flags or, at least, ignore them. This allows for any
+script or custom executable to be used when a \*(L"sed\*(R" script is considered
+inadequate.
+.SS "Filtering examples"
+.IX Subsection "Filtering examples"
+As an example, suppose your titles look like this::
+.PP
+.Vb 1
+\& Artist \- Title (radiobanner)
+.Ve
+.PP
+You can write a sed expression or script containing::
+.PP
+.Vb 1
+\& s/ (radiobanner)$//
+.Ve
+.PP
+to remove the trailing part. This facility can also be used to uniform file
+names, invert Artist/Title positions and so on. Clever use of the pattern space
+can also be used to merge albums. sed alone can be used to debug expressions,
+eg::
+.PP
+.Vb 1
+\& echo "test title" | sed \-e \*(Aqexpr\*(Aq
