NAME

       GAP - Groups, Algorithms and Programming

DESCRIPTION

       GAP  is	a  system  for computational discrete algebra with particular emphasis on computational group theory, but which has already proved
       useful also in other areas. In the example text, gap is used to analyse Rubik's Cube using group theory. A kernel implements a  pascal-like
       language.

OPTIONS

       usage: gap [OPTIONS] [FILES]

	      run the Groups, Algorithms and Programming system, Version 4.4.8

       -h     print this help and exit

       -b     disable/enable the banner

       -q     enable/disable quiet mode

       -e     disable/enable quitting on <ctr>-D

       -f     force line editing

       -n     prevent line editing

       -x <num>
	      set line width

       -y <num>
	      set number of lines

       -g     show GASMAN messages (full garbage collections)

       -g -g  show GASMAN messages (all garbage collections)

       -m <mem>
	      set the initial workspace size

       -o <mem>
	      set hint for maximal workspace size (GAP may allocate more)

       -K <mem>
	      set maximal workspace size (GAP never allocates more)

       -c <mem>
	      set the cache size value

       -a <mem>
	      set amount to pre-malloc-ate postfix 'k' = *1024, 'm' = *1024*1024, 'g' = *1024*1024*1024

       -l <paths>
	      set the GAP root paths

       -r     disable/enable reading of the '.gaprc' file

       -A     disable/enable autoloading of GAP packages

       -B <name>
	      current architecture

       -D     enable/disable debugging the loading of library files

       -M     disable/enable loading of compiled modules

       -N     disable/enable check for completion files

       -T     disable/enable break loop

       -X     enable/disable CRC for comp. files while reading

       -Y     enable/disable CRC for comp. files while completing

       -i <file>
	      change the name of the init file

       -L <file>
	      restore a saved workspace

       -R     prevent restoring of workspace (ignoring -L)

	      Boolean options (b,q,e,r,A,D,M,N,T,X,Y) toggle the current value each time they are called. Default actions are indicated first.
