I have been using custom command files (macro files). Originally I
called them lattice.sty, more recently, newlattice.sty.<br>
They are discussed in detail in my LaTeX books.<br>
<br>
The truth is, however, that these files evolve. New concepts come up,
requiring new standard notations, reflected in new custom commands. The
newlattice.sty of today may not properly typeset an older paper. Since
these files are small, <br>
around 6K, there is a simple solution. Place a copy in the folder with
the new paper.<br>
<br>
No need for Dropbox and links.<br>
