documentation.html: add a paragraph on W. Lindner's Tensor Calculus
relatedprojects.html: update the description of Yamwi
plot is part of the core of Maxima, so it is compiled and saved in the Maxima image at build time; draw is a share package that is optional and only compiled when it is first loaded at run time. There are other packages like this.
I can confirm the specifics of the original bug report. I had clean debian testing installation on a VM, installed the maxima package and then tried to load draw. That failed and the errors indicated the problem was the maxima package depends on gcc. This is a bug in the debian maxima package. I don't think the debian bug has been fixed. The patch does not address the missing dependency. I think that bug report was closed prematurely. But, I do think this bug report can be closed, because it is not...
Patch.
tex-array creates invalid double subscript
The interaction of the tex DWIM rule for subscripts and itensor's convention causes double subscript errors in some tex. demo(bradic); contains such an example. The input line 48, ishow(e([m,n],[])=canform(%*16*%pi/sqrt(-determinant(g))))$ produces a large expression that, when tex-ed, contains the following mal-formed code: {\it ichr}_{2}_{{\it \%4 \%}_{5}} The proposed patch would produce the valid tex: {\it ichr}_{2}_{{\it \%4 \%5\ }}
tex output for an input label %i1 is inconsistent
