+.SH
+Module flp
+.LP
+The flp module loads fl-forms from fd files, as generated
+by fdesign. The module is designed to be flexible enough to allow
+almost anything to be done with the loaded form.
+.LP
+Loadform defines 
+two types of functions: functions to parse fd files and functions to
+create the forms from the templates returned by the parse functions.
+There are fairly low-level create functions that create single objects,
+and convenience routines that create complete forms, including callbacks,
+etc.
+.LP
+The exception flp.error is raised whenever an error occurs while parsing a forms
+definition file or creating a form.
+.SH 2
+Parsing functions
+.LP
+There are two parsing functions, parse_form() and parse_forms(). They
+take the following form:
+.LP
+.ft C
+ftuple = parse_form(filename, formname)
+.br
+ftdict = parse_forms(filename)
+.IP
+Parse_form parses a single form, and returns a tuple (ftmp, otmplist).
+Ftmp is a template for a form, otmplist is a list of templates for
+objects. See below for a description of these templates.
+.IP
+Parse_forms parses all forms in an fd file. It returns a dictionary of
+(ftmp, otmplist) tuples, indexed by formname.
+.IP
+Filename is the name of the forms definition file to inspect. The functions
+appends '.fd' if needed, and use 'sys.path' to locate the file.
+.IP
+formname is the name of the form to load. This argument is mandatory,
+even if the file only contains one form.
+.LP
+The form template and object template are structures that contain all
+the information read from the fd file, in 'natural' form. A form
+template record contains the following fields:
+.IP
+.nf
+"Name", the name of the form;
+"Width", the width of the form;
+"Height", the height of the form; and
+"Numberofobjects", the number of objects in the form.
+.LP
+An object template contains the following fields:
+.IP
+.nf
+"Class", the class of object (eg. FL.BUTTON);
+"Type", the sub-class (eg. FL.NORMALBUTTON);
+"Box", a list with four members: [x, y, width, height];
+"Boxtype", the type of box (eg. FL.DOWNBOX);
+"Colors", a list with the two object colors;
+"Alignment", the label alignment (eg. FL.ALIGNLEFT); 
+"Style", the label style (eg. FL.BOLDSTYLE);
+"Lcol", the label color;
+"Label", a string containing the label;
+"Name", a string containing the name of the object;
+"Callback", a string containing the callback routine name; and
+"Argument", a string containing the callback routine extra argument.
+.SH
+Low-level create routines.
+.LP
+The three low-level creation routines are called as follows:
+.LP
+.ft C
+form = create_form(form_template)
+.IP
+Create an fl form from a form template. Returns the form created.
+.LP
+.ft C
+obj = create_object(form, obj_template)
+.IP
+Create an object in an fl form. Return the new object.
+An error is raised if the object has a callback routine.
+.SH
+High-level create routines.
+.LP
+The 'standard' way to handle forms in python is to define a class
+that contains the form and all the objects (insofar as they are named),
+and that defines all the callback functions, and use an instance of
+this class to handle the form interaction.
+Flp contains three routines that simplify handling this paradigm:
+.LP
+.ft C
+create_full_form(instance, ftuple)
+.IP
+This routine takes an instance of your form-handling class and an
+ftuple (as returned by the parsing routines) as parameters. It inserts
+the form into the instance, defines all object names and arranges that
+the callback methods are called. All the names inserted into the
+instance are the same as the names used for the objects, etc. in the
+fd file.
+.LP
+.ft C
+merge_full_form(instance, form, ftuple)
+.IP
+This function does the same as create_full_form, only it does not create
+the form itself nor the 'background box' that fdesign automatically
+adds to each form. This is useful if your class inherits a superclass
+that already defines a skeleton form (with 'OK' and 'Cancel' buttons,
+for instance), and you want to merge the new form into that existing
+form. The 'form' parameter is the form to which the new objects are
+added.
+.LP
+If you use the paradigm sketched here but need slightly more control
+over object creation there is a routine that creates a single object
+and inserts its name (and arranges for the callback routine to be
+called):
+.LP
+.ft C
+create_object_instance(instance, form, obj_template)

+Interface to CD-ROM player.
+
+This module implements an interface to the built-in cd module.  The
+intention is to provide a more user-friendly interface than the
+built-in module.
+
+The module defines a class Readcd with several methods.  The
+initialization of the class will try to open the CD player.  This
+means that initialization will fail if the CD player is already in
+use.  A RuntimeError will be raised by the cd module in that case.
+
+The way to work with this module is as follows.  The user specifies
+the parts of the CD that are to be read and he specifies callback
+functions which are to be called by the system.  At some point he can
+tell the system to play.  The specified parts of the CD will then be
+read and the callbacks will be called.
+
+Initialization.
+===============
+
+r = readcd.Readcd([cd-player [, mode]])
+
+The optional arguments are the name of the CD device and the mode.
+When "mode" is not specified, it defaults to 'r' (which is the only
+possible value); when "cd-player" also isn't specified, it defaults
+to "None" which indicates the default CD player.
+
+Methods.
+========
+
+eject() -- Eject the CD from the player.
+
+reset() -- Reset the list of data stretches to be played.
+
+appendtrack(track) -- Append the specified track to the list of music
+stretches.
+
+appendstretch(first, last) -- Append the stretch from "first" to "last"
+to the list of music stretches.  Both "first" and "last" can be in one
+of four forms.  "None": for "first", the beginning of the CD, for
+"last" the end of the CD; a single integer: a track number--playing
+starts at the beginning of the track or ends at the end of the
+specified track; a three-tuple: the absolute time from the start of
+the CD in minutes, seconds, frames; a four-tuple: track number and
+relative time within the track in minutes, seconds, frames.
+
+settracks(tracklist) -- The argument is a list of integers.  The list
+of stretches is set to argument list.  The old list is discarded.
+
+setcallback(type, func, arg) -- Set a callback function for "type".
+The function will be called as func(arg, type, data) where "arg" is
+the third argument of setcallback, "type" is the type of callback,
+"data" is type-dependent data.  See the CDsetcallback(3) manual page
+for more information.  The possible "type" arguments are defined in
+the CD module.
+
+removecallback(type) -- Remove the callback for "type".
+
+gettrackinfo([tracklist]) -- Return a list of tuples.  Each tuple
+consists of start and length information of a track.  The start and
+length information consist of three-tuples with minutes, seconds and
+frames.  The optional tracklist argument gives a list of interesting
+track numbers.  If no tracklist is specified, information about all
+tracks is returned.
+
+getstatus() -- Return the status information of the CD.
+
+play() -- Play the preprogrammed stretches of music from the CD.  When
+nothing was programmed, the whole CD is played.
+
+Specifying stretches.
+=====================
+
+There are three methods available to specify a stretch of music to be
+played.  The easiest way is to use "settracklist(tracklist)" with which
+a list of tracks can be specified.  "settracklist(tracklist)" is
+equivalent to the sequence
+	reset()
+	for track in tracklist:
+		appendtrack(track)
+
+The next method is "appendtrack(track)" with which a whole track can be
+added to the list of music to be played.  "appendtrack(track)" is
+equivalent to "appendstretch(track, track)".
+
+The most complete method is "appendstretch(first, last)".  Using this
+method, it is possible to specify any stretch of music.
+
+When two consecutive tracks are played, it is possible to choose
+whether the pause that may be between the tracks is played as well or
+whether the pause should be skipped.  When the end of a stretch is
+specified using a track number and the next stretch starts at the
+beginning of the following track and that was also specified using the
+track number (that is, both were specified as integers, not as tuples),
+the pause is played.  When either value was specified using absolute
+time or track-relative time (that is, as three-tuple or as
+four-tuple), the pause will not be played.
+
+Errors.
+=======
+
+When an error occurs, an exception will be raised.  Depending on where
+the error occurs, the exception may either be "readcd.Error" or
+"RuntimeError".
