-add [MOVES|$ID1|@ID1] $ID2\n\

-DESCRIPTION\n\
-Appends either MOVES, the scramble memorized under $ID1 or the output sequence\n\
-memorized under @ID1 at the end of the scramble memorized under $ID2. If none\n\
-of MOVES, $ID1 or @ID1 is specified, the user will be asked to type the moves.\n\
-Menmonic: \"add x to y\" or just \"add to y\".\n\
-\n\
-EXAMPLES\n\
-add $1\n\
-  The user is required to type the moves that will be appended to $1.\n\
-add F R B $1\n\
-  Appends the moves F R B to scramble $1. Now scramble $1 ends with F R B.\n\

-********************* NISSY: a cube solver and FMC helper *********************\n\
-*******************************************************************************\n\
-\n\
-If you just want to solve the cube, type 'solve' followed by the scramble. This\n\
-will not always give you an optimal solution, unless it is 10 moves or less or\n\
-you use the \"o\" option. Finding the optimal solution might take very long if it\n\
-is 16 moves or more, especially for the first time.\n\
-\n\
-Now the fun stuff. With nissy you can save and manipulate move sequences, for\n\
-example:\n\
-\n\
-nissy-# save R' U' F\n\
-$1:     R' U' F\n\
-nissy-# add L2D' $1\n\
-$1:     R' U' F L2 D'\n\
-\n\
-You can then ask nissy to solve certain substepson a saved scramble:\n\
-\n\
-nissy-# eo axis=rl $1\n\
-@1:     U D F' R (4)\n\
-\n\
-And of course it uses also NISS, if you ask:\n\
-\n\
-nissy-# eo niss axis=rl $1\n\
-@1:     (R) (1)\n\
-\n\
-Notice that the sequences you save are marked with a $, while the \"output\"\n\
-sequences are marked with @. The difference between these two type of sequences\n\
-is that those marked with @ are temporary and get lost once you get new output.\n\
-Most commands accept as input either a move sequence typed out, a $-sequence or\n\
-a @-sequence. For example, you can however save a @-sequence and make it\n\
-persistent:\n\
-\n\
-nissy-# save @1\n\
-$2:     (R)\n\
-\n\
-Nissy also understands NISS. Let's see a more complicated example where you\n\
-save a scramble, ask for some EOs (using NISS) and then a DR on inverse:\n\
-\n\

-It outputs at most 10 equivalent optimal sequences for each replaceable part.\n\

-DESCRIPTION\n\
-Memorizes the scramble specified by MOVES, given as input or temporarily saved\n\

-\n\
-DESCRIPTION\n\
-Solves the given scramble, which can be given as a sequence of moves or as $ID\n\
-or @ID. If none is given, the user can type it on the next line.\n\
-The algorithm first tries to find a short (<=10 moves) solution, and then\n\
-switches to a 2-step algorithm (unless the option \"o\" is specified, in which\n\
-case it keeps looking for an optimal solution).\n\
-The first time it uses the 2-step algorithm it needs to load some tables, which\n\
-can take a few seconds. It runs much faster after that. If the option \"o\" is\n\
-specified, the first time it loads some large tables, which can take a minute\n\
-or two.\n\

-                   Solutions will only be found if they are <=10 moves.\n\
