+ * Standard Version: 1.0, Revision: 1.0
+ *
+ * The GTF Document contains the following Copyright information:

+ * Association. Duplication of this document within VESA member

+ * While every precaution has been taken in the preparation
+ * of this standard, the Video Electronics Standards Association and

+ * and make no warranties, expressed or implied, of functionality
+ * of suitability for any purpose. The sample code contained within
+ * this standard may be used without restriction.
+ *
+ *
+ *
+ * The GTF EXCEL(TM) SPREADSHEET, a sample (and the definitive)
+ * implementation of the GTF Timing Standard, is available at:
+ *
+ * ftp://ftp.vesa.org/pub/GTF/GTF_V1R1.xls
+ *
+ *
+ *
+ * This program takes a desired resolution and vertical refresh rate,
+ * and computes mode timings according to the GTF Timing Standard.
+ * These mode timings can then be formatted as an XFree86 modeline
+ * or a mode description for use by fbset(8).
+ *
+ *
+ *
+ * NOTES:
+ *
+ * The GTF allows for computation of "margins" (the visible border
+ * surrounding the addressable video); on most non-overscan type
+ * systems, the margin period is zero. I've implemented the margin
+ * computations but not enabled it because 1) I don't really have
+ * any experience with this, and 2) neither XFree86 modelines nor
+ * fbset fb.modes provide an obvious way for margin timings to be
+ * included in their mode descriptions (needs more investigation).
+ *
+ * The GTF provides for computation of interlaced mode timings;
+ * I've implemented the computations but not enabled them, yet.
+ * I should probably enable and test this at some point.
+ *
+ *
+ *
+ * TODO:
+ *
+ * o Add support for interlaced modes.
+ *
+ * o Implement the other portions of the GTF: compute mode timings
+ * given either the desired pixel clock or the desired horizontal
+ * frequency.
+ *
+ * o It would be nice if this were more general purpose to do things
+ * outside the scope of the GTF: like generate double scan mode
+ * timings, for example.
+ *
+ * o Printing digits to the right of the decimal point when the
+ * digits are 0 annoys me.
+ *
+ * o Error checking.
