+{ These defines indicate whether to include various optional functions.
+  Undefining some of these symbols will produce a smaller but less capable
+  library.  Note that you can leave certain source files out of the
+  compilation/linking process if you've #undef'd the corresponding symbols.
+  (You may HAVE to do that if your compiler doesn't like null source files.)}
+
+
+{ Arithmetic coding is unsupported for legal reasons.  Complaints to IBM. }
+
+{ Capability options common to encoder and decoder: }
+
+{$define DCT_ISLOW_SUPPORTED}     { slow but accurate integer algorithm }
+{$define DCT_IFAST_SUPPORTED}     { faster, less accurate integer method }
+{$define DCT_FLOAT_SUPPORTED}     { floating-point: accurate, fast on fast HW }
+
+{ Encoder capability options: }
+
+{$undef C_ARITH_CODING_SUPPORTED}    { Arithmetic coding back end? }
+{$define C_MULTISCAN_FILES_SUPPORTED} { Multiple-scan JPEG files? }
+{$define C_PROGRESSIVE_SUPPORTED}     { Progressive JPEG? (Requires MULTISCAN)}
+{$define ENTROPY_OPT_SUPPORTED}       { Optimization of entropy coding parms? }
+{ Note: if you selected 12-bit data precision, it is dangerous to turn off
+  ENTROPY_OPT_SUPPORTED.  The standard Huffman tables are only good for 8-bit
+  precision, so jchuff.c normally uses entropy optimization to compute
+  usable tables for higher precision.  If you don't want to do optimization,
+  you'll have to supply different default Huffman tables.
+  The exact same statements apply for progressive JPEG: the default tables
+  don't work for progressive mode.  (This may get fixed, however.) }
