+ * track and display the cursor. This gives better
+ * performance as the display calls don't have to cross
+ * the kernel boundary. Unfortunately, this mode has
+ * synchronization issues with the user land X server
+ * and isn't currently used.
+ *
+ * Hardware cursor support lets the hardware handle these
+ * details.
+ *
+ * Kernel and hardware cursor mode only work for cursors
+ * up to a certain size, currently 16x16 pixels. If a
+ * bigger cursor is set, we fallback to X cursor mode.

+    Realizing the Darwin hardware cursor (ie. converting from the
+    X representation to the IOKit representation) is complicated
+    by the fact that we have three different potential cursor
+    formats to go to, one for each bit depth (8, 15, or 24).
+    The IOKit formats are documented in IOFramebufferShared.h.
+    X cursors are represented as two pieces, a source and a mask.
+    The mask is a bitmap indicating which parts of the cursor are 
+    transparent and which parts are drawn.  The source is a bitmap
+    indicating which parts of the non-transparent portion of the the
+    cursor should be painted in the foreground color and which should
+    be painted in the background color. The bitmaps are given in
+    32-bit format with least significant byte and bit first.
+    (This is opposite PowerPC Darwin.)

+ * This module converts keysym values into the corresponding ISO 10646
+ * (UCS, Unicode) values.
+ *
+ * The array keysymtab[] contains pairs of X11 keysym values for graphical
+ * characters and the corresponding Unicode value. The function
+ * keysym2ucs() maps a keysym onto a Unicode value using a binary search,
+ * therefore keysymtab[] must remain SORTED by keysym value.
+ *
+ * The keysym -> UTF-8 conversion will hopefully one day be provided
+ * by Xlib via XmbLookupString() and should ideally not have to be
+ * done in X applications. But we are not there yet.
+ *
+ * We allow to represent any UCS character in the range U-00000000 to
+ * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
+ * This admittedly does not cover the entire 31-bit space of UCS, but
+ * it does cover all of the characters up to U-10FFFF, which can be
+ * represented by UTF-16, and more, and it is very unlikely that higher
+ * UCS codes will ever be assigned by ISO. So to get Unicode character
+ * U+ABCD you can directly use keysym 0x0100abcd.
+ *
+ * NOTE: The comments in the table below contain the actual character
+ * encoded in UTF-8, so for viewing and editing best use an editor in
+ * UTF-8 mode.

+ * This module converts keysym values into the corresponding ISO 10646
+ * (UCS, Unicode) values.
+ *
+ * The array keysymtab[] contains pairs of X11 keysym values for graphical
+ * characters and the corresponding Unicode value. The function
+ * keysym2ucs() maps a keysym onto a Unicode value using a binary search,
+ * therefore keysymtab[] must remain SORTED by keysym value.
+ *
+ * The keysym -> UTF-8 conversion will hopefully one day be provided
+ * by Xlib via XmbLookupString() and should ideally not have to be
+ * done in X applications. But we are not there yet.
+ *
+ * We allow to represent any UCS character in the range U-00000000 to
+ * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
+ * This admittedly does not cover the entire 31-bit space of UCS, but
+ * it does cover all of the characters up to U-10FFFF, which can be
+ * represented by UTF-16, and more, and it is very unlikely that higher
+ * UCS codes will ever be assigned by ISO. So to get Unicode character
+ * U+ABCD you can directly use keysym 0x0100abcd.
+ *
+ * Author: Markus G. Kuhn <mkuhn@acm.org>, University of Cambridge, April 2001

+.SH NAME
+getconfig - meta configuration files for getconfig(1)
+.SH SYNOPSIS
+.B \(**.cfg
+.SH DESCRIPTION
+.B getconfig
+is a programatic interface that is used by the
+.B XFree86
+server to get configuration information about video hardware when
+operating without an
+.B XF86Config
+file.
+.PP
+This implementation of
+.B getconfig
+is written in perl.  It processes rules from meta-configuration files.
+All meta-configuration files have a
+.I .cfg
+suffix.
+.PP
+Lines starting with a pound-sign (#) are comments, and are ignored.
+Blank lines that consist only of white space are also treated as comments
+and ignored.
+.PP
+The first non-comment line must be a signature string followed by
+the file format version number.  The signature string is
+.PP
+.RS 4
+.nf
+"XFree86 Project getconfig rules file.\ \ Version: "
+.fi
+.RE
+.PP
+The currently defined version is "1.0".  Files that do not have the
+correct signature string are ignored.
+.PP
+The remaining non-comment lines define rules.  The start of a new rule
+is indicated by a line with no leading white space.  Subsequent lines
+making up a rule must be indented with white space.  Logical lines within
+a rule may be split over multiple physical lines by using the usual
+continuation convention ('\e' at the end of the line).  The first logical
+line of each rule is a perl expression.  It may be any valid perl
+expression whose evaluated (with 'eval') result may be used as the
+argument to a perl 'if' statement.  The second logical line should be
+the name of the XFree86 video driver to use when the rule is true, and
+subsequent logical lines of each rule, if present, are additional
+configuration output for the video device's
+.B XF86Config
+.B Device
+section.  The driver name and additional lines of configuration information
+are written to standard output when the rule is chosen as the successful
+rule.
+.PP
+Pseudo rules consisting of perl expressions may be present in the file
+for the purpose of defining custom perl variables or setting the weight
+to use for the following rules.  Pseudo rules are rules that consist of
+a single logical line only, and the are never candidates themselves for the
+successful rule.
+.PP
+Several perl variables are pre-defined, and may be used within rules.
+They include:
+.PP
+.RS 4
+.nf
+.BR "$vendor                 " "PCI vendor ID"
+.BR "$device                 " "PCI device ID"
+.BR "$revision               " "PCI revision ID"
+.BR "$subsys                 " "PCI subsystem ID"
+.BR "$subsysVendor           " "PCI subsystem vendor ID"
+.BR "$class                  " "PCI class"
+.BR "$XFree86Version         " "XFree86 version, as a 'v' string"
+.BR "$XFree86VersionNumeric  " "XFree86 numeric version"
+.BR "$XFree86VersionMajor    " "XFree86 major version"
+.BR "$XFree86VersionMinor    " "XFree86 minor version"
+.BR "$XFree86VersionPatch    " "XFree86 patch version"
+.BR "$XFree86VersionSnap     " "XFree86 snap version"
+.BR "$weight                 " "current rule weight"
+.fi
+.RE
+.PP
+The
+.B $weight
+variable deterines the weight of the rules as they are processed.  The
+weight for subsequent rules may be set with a pseudo rule that sets or
+changes the value of
+.BR $weight .
+The default weight, and the weight used for built-in rules is 500.  The
+meta-configuration files are processed in an unpredictable order.  The
+weighting of the rules is used to determine their relative priority
+.PP
+After processing all of the rules, both built-in and those read from
+the meta-configration files, the
+.B getconfig
+program chooses as the successful rule the last and highest weighted
+rule that evaluates to true.
+.SH FILES
+.I .cfg
+files located in the search path.  The search path typically specified
+by the
+.B XFree86
+server is:

+.I /etc/X11
+.I __projectroot__/etc/X11
+.I <modulepath>
+.I __projectroot__/lib/X11/getconfig

+.SH NAME
+getconfig - get configuration information for the XFree86 server
+.SH SYNOPSIS
+.B getconfig
+.RI [ option
+.IR ... ]
+.SH DESCRIPTION
+.B getconfig
+is a programatic interface that is used by the
+.B XFree86
+server to get configuration information about video hardware when
+operating without an
+.B XF86Config
+file.
+.PP
+This implementation of
+.B getconfig
+is written in perl.  It processes a prioritized and ordered list of
+rules supplied internally and from meta-configuration files.  The rules
+are in the form of perl expressions.
+.B getconfig
+writes to standard output the XF86Config-style configuration data
+specified by the last highest priority rule that evaluates to true.
+Information about the format of the meta-configuration files can be
+found in the getconfig(__filemansuffix__) manual page.
+.SH OPTIONS
+.TP 8
+.BI \-I " search-path"
+Specify the search path to use for meta-config files.
+.I search-path
+is a comma-separated list of directories to search.  Each directory in
+the search path is searched for files with a
+.I .cfg
+suffix.  Each such file is opened and checked for a valid signature
+string.  Rules are read from files with a valid signature string and
+appended to the list of rules to evaluate.  If no search path is specified,
+only the internally supplied configuration rules will be used.
+.TP 8
+.B \-D
+Enable debugging output.
+.TP 8
+.B \-V
+Print out the version information and exit.
+.TP 8
+.BI \-X " XFree86-version"
+Specify the XFree86 version in numeric (integer) form.
+.TP 8
+.BI \-b " subsys-id"
+Specify the PCI subsystem ID of the video device.
+.TP 8
+.BI \-c " class"
+Specify the PCI class of the video device.
+.TP 8
+.BI \-d " device-id"
+Specify the PCI devide ID of the video device.
+.TP 8
+.BI \-r " revision"
+Specify the PCI revision of the video device.
+.TP 8
+.BI \-s " subsysvendor-id"
+Specify the PCI subsystem vendor ID of the video device.
+.TP 8
+.BI \-v " vendor-id"
+Specify the PCI vendor ID of the video device.
