Aleph is a version of the TeX program modified for multilingual
typesetting. It uses Unicode, and has additional primitives for
(among other things) bidirectional typesetting.
Aleph's command line options are similar to those of TeX.

utility can be used to query the values of the variables.
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

files, as TeX often generates files that need to be subsequently
read; for input, no suffixes (such as ``.tex'') are added by default,
the input name is simply checked as given.

Web2C: A TeX implementation
This version of Aleph implements a number of optional extensions.
In fact, many of these extensions conflict to a greater or lesser
extent with the definition of Aleph. When such extensions are
enabled, the banner printed when Aleph starts is changed to print
This version of Aleph fails to trap arithmetic overflow when
dimensions are added or subtracted. Cases where this occurs are rare,

The primary authors of Aleph are John Plaice and Yannis Haralambous.
It is currently maintained (for severe bug fixes only) by Taco Hoekwater.
