The forloop package provides the command \forloop for the user.
To install this package, run forloop.ins through LaTeX. This will generate
a file called forloop.sty. Put this file somewhere where LaTeX will find
it---for instance localtexmf/tex/latex/forloop/ (note that you will need
to create the folder forloop).
If you are using MikTeX, you then need to refresh the file name database
by using MikTeX Options
