One caveat: In most Aleph formats, you cannot use ~ in a filename you
give directly to Aleph, because ~ is an active character, and hence is
expanded, not taken as part of the filename. Other programs, such as
Metafont, do not have this problem.
Normally, Aleph puts its output files in the current directory. If
any output file cannot be opened there, it tries to open it in the
directory specified in the environment variable TEXMFOUTPUT.
There is no default value for that variable. For example, if you say

In fact, many of these extensions conflict to a greater or lesser
