+"These are continually updated to coincide with the latest developments that\n"\
+"occur and as a result should provide you with nearly the best quality\n"\
+"currently possible from LAME.\n"\
+"\n"\
+"To activate these presets:\n"\
+"\n"\
+" For VBR modes (generally highest quality):\n"\
+"\n"\
+" \"preset=standard\" This preset should generally be transparent\n"\
+" to most people on most music and is already\n"\
+" quite high in quality.\n"\
+"\n"\
+" \"preset=extreme\" If you have extremely good hearing and similar\n"\
+" equipment, this preset will generally provide\n"\
+" slightly higher quality than the \"standard\"\n"\
+" mode.\n"\
+"\n"\
+" For CBR 320kbps (highest quality possible from the preset switches):\n"\
+"\n"\
+" \"preset=insane\" This preset will usually be overkill for most\n"\
+" people and most situations, but if you must\n"\
+" have the absolute highest quality with no\n"\
+" regard to filesize, this is the way to go.\n"\
+"\n"\
+" For ABR modes (high quality per given bitrate but not as high as VBR):\n"\
+"\n"\
+" \"preset=<kbps>\" Using this preset will usually give you good\n"\
+" quality at a specified bitrate. Depending on the\n"\
+" bitrate entered, this preset will determine the\n"\
+" optimal settings for that particular situation.\n"\
+" While this approach works, it is not nearly as\n"\
+" flexible as VBR, and usually will not attain the\n"\
+" same level of quality as VBR at higher bitrates.\n"\
+"\n"\
+"The following options are also available for the corresponding profiles:\n"\

+" <fast> standard\n"\
+" <fast> extreme\n"\

+" <cbr> (ABR Mode) - The ABR Mode is implied. To use it,\n"\
+" simply specify a bitrate. For example:\n"\
+" \"preset=185\" activates this\n"\
+" preset and uses 185 as an average kbps.\n"\
+"\n"\
+" \"fast\" - Enables the new fast VBR for a particular profile. The\n"\
+" disadvantage to the speed switch is that often times the\n"\
+" bitrate will be slightly higher than with the normal mode\n"\
+" and quality may be slightly lower also.\n"\
+" Warning: with the current version fast presets might result in too\n"\
+" high bitrate compared to regular presets.\n"\
+"\n"\
+" \"cbr\" - If you use the ABR mode (read above) with a significant\n"\
+" bitrate such as 80, 96, 112, 128, 160, 192, 224, 256, 320,\n"\
+" you can use the \"cbr\" option to force CBR mode encoding\n"\
