(This derives form the thread about metafun.mem) As I have used till now only texshop, I was going to try the distro form pragma-ade. I downloaded it but I do not know what to do. As they are binaries I supposed I have not to compile anything. Should I simply put the folder in the right place? The Readme is quite vague. I put it in usr/local, tried to run from terminal the texexec bin but obtained: apples-Computer:/ apple$ /usr/local/tex/texmf-macosx/bin/texexec --h /usr/local/tex/texmf-macosx/bin/texexec: line 2: texmfstart: command not found What have I to do to use the most recent distro from pragma? More, I really cannot understand what's going on when I invoke "typeset context" form inside TeXShop. Luckily, something happens and I have my nice pdfs. This is default engine as stated by TeXShop. /usr/local/teTeX/bin/powerpc-apple-darwin-current If I go there, I find many binaries, and there's a texexec. If I invoke it directly form terminal I obtain: apples-Computer:/ apple$ /usr/local/teTeX/bin/powerpc-apple-darwin6.8/texexec -h `texexec.pl' not found. If I invoke texexec from terminal, default is located in sw/bin. It's 3.1 version: apples-Computer:/ apple$ which texexec /sw/bin/texexec apples-Computer:/ apple$ texexec -h TeXExec 3.1 - ConTeXt / PRAGMA ADE 1997-2002 (I know virtually nothing of bash, I grabbed some commands here and there) I'm getting a bit depressed... -a-
