In order to keep my preambles, etc as short as possible, I use .sty  
files. Since I don't know what I am doing, I proceed by trials and  
error which works but at the cost of many different versions.

Not only to synchronize between machines, but in general to keep  
everything that belongs to a given version together, I wanted to keep  
the sty files together with the project files and I used symlinks to  
these sty files in texmf > tex > Latex.

With a little bit of trial and error, I managed to do that and it  
worked for one tome but not for the other. So, I remembered having  
downloaded SymbolicLinker which Vosberg had mentioned on On Apr 6,  
2009, at 6:19 AM, RA.

And that worked exactly as advertised.

What I will also do is to make a copy of each tome on my laptop and  
create symlinks there too. Then, what I hope will work is that the  
symlinks will not notice when I change a file to a new version--with  
the same name of course.

Grateful regards to both Spiegel and Vosberg
