GAP \- Groups, Algorithms and Programming
.SH SYNOPSIS

[\fI\,OPTIONS\/\fR] [\fI\,FILES\/\fR]
.SH DESCRIPTION
GAP is a system for computational discrete algebra, with particular emphasis
on Computational Group Theory. GAP provides a programming language, a library
of thousands of functions implementing algebraic algorithms written in the GAP
language as well as large data libraries of algebraic objects. GAP is used in
research and teaching for studying groups and their representations, rings,
vector spaces, algebras, combinatorial structures, and more.

\fB\-h\fR, \fB\-\-help\fR
print this help and exit
.TP
\fB\-b\fR, \fB\-\-banner\fR
disable/enable the banner
.TP
\fB\-q\fR, \fB\-\-quiet\fR
enable/disable quiet mode
.TP
\fB\-e\fR
disable/enable quitting on <ctr>\-D
.TP
\fB\-f\fR
force line editing
.TP
\fB\-n\fR
prevent line editing
.TP
\fB\-E\fR, \fB\-\-readline\fR
disable/enable use of readline library (if
possible)
.TP
\fB\-x\fR, \fB\-\-width\fR
<num>     set line width
.TP
\fB\-y\fR, \fB\-\-lines\fR
<num>     set number of lines
.TP
\fB\-g\fR, \fB\-\-gasinfo\fR
show GASMAN messages (full/all/no garbage
collections)
.TP
\fB\-m\fR, \fB\-\-minworkspace\fR <mem>
set the initial workspace size
.TP
\fB\-o\fR, \fB\-\-maxworkspace\fR <mem>
set hint for maximal workspace size (GAP may
allocate more)
.TP
\fB\-K\fR, \fB\-\-limitworkspace\fR <mem>
set maximal workspace size (GAP never
allocates more)
.TP
\fB\-c\fR
<mem>     set the cache size value
.TP
\fB\-s\fR
<mem      set the initially mapped virtual memory
.TP
\fB\-a\fR
<mem>     set amount to pre\-malloc\-ate
postfix 'k' = *1024, 'm' = *1024*1024,
\&'g' = *1024*1024*1024
.TP
\fB\-l\fR, \fB\-\-roots\fR
<paths>   set the GAP root paths
Directories are separated using ';'.
Putting ';' on the start/end of list appends
directories to the end/start of existing list
of root paths
.TP
\fB\-r\fR
disable/enable user GAP root dir
GAPInfo.UserGapRoot
.TP
\fB\-A\fR
disable/enable autoloading of suggested
GAP packages
.TP
\fB\-B\fR
<name>    current architecture
.TP
\fB\-D\fR
enable/disable debugging the loading of files
.TP
\fB\-M\fR
disable/enable loading of compiled modules
.TP
\fB\-N\fR
unused, for backward compatibility only
.TP
\fB\-O\fR
disable/enable loading of obsolete files
.TP
\fB\-X\fR
enable/disable CRC checking for compiled modules
.TP
\fB\-T\fR
disable/enable break loop
.TP
\fB\-i\fR
<file>    change the name of the init file
.TP
\fB\-L\fR
<file>    restore a saved workspace
.TP
\fB\-R\fR
prevent restoring of workspace (ignoring \fB\-L\fR)
.TP
\fB\-p\fR
enable/disable package output mode
.TP
\fB\-\-prof\fR
<file>    Run ProfileLineByLine(<filename>) on GAP start

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