Probably you will find what you need at:
http://www.gap-system.org/Doc/doc.html
It links to many good documents, including:
A "How to" guide: http://www.usna.edu/Users/math/wdj/gap/GAPconstructions.html
The current reference manual: http://www.gap-system.org/Manuals/doc/htm/ref/chapters.htm
If you type:
grp := DihedralGroup(12);
aut := AutomorphismGroup(grp);
inn := grp/Center(grp);
StructureDescription(aut);
StructureDescription(inn);
into GAP then you will see:
gap> grp := DihedralGroup(12);
<pc group of size 12 with 3 generators>
gap> aut := AutomorphismGroup(grp);
<group of size 12 with 3 generators>
gap> inn := grp/Center(grp);
Group([ f1, f2^2, f2 ])
gap> StructureDescription(aut);
"D12"
gap> StructureDescription(inn);
"S3"
