+ v1.1
+ by eKid
+
+to make the snes life a little easier
+
+how it's used...
+
+1. Run the program.
+2. Click Import .PCX to load a pcx file.
+3. Image should display in top-left corner.
+4. (Optional) Swap around the colors in the palette by left clicking to select, and right clicking to swap.
+5. Select Bit-Depth for export and set tile size (bottom left corner).
+6. Click Export .inc and choose a filename to export to.
+7. Your Done!
+
+------------------------
+
+Command Line mode
+
+Usage:
+  pcx2snes in.pcx [-oOut.inc] [-bBits] [-nName] [-d (16x16)] [-sColor]
+
+  -parameters in brackets are all optional
+  -there must be no space between the prefix and value
+
+Parameter Description:
+
+  -o		Specifies file to output to, if not supplied it will use the input file with a ".inc" extension.
+  -b		Specifies bit depth, can be 2/4/8 for 4/16/256 colors, if not supplied it will use the bit depth of the PCX.
+  -n		Specifies name to use as a prefix of the exported array, default is "Untitled".
+  -s		Specifies an index to swap color 0 with, this is optional (mainly for transparency).
+  -d		Tells pcx2snes to arrange for 16x16 mode.
