Arch vs tla
Google asked me: what is the difference between arch and tla?
The short answer is that they are two names for the same thing. The
project was originally conceived of as arch
: I suppose the idea
of an arch connotes elegance, and it has a r-c
sound to suggest
revision control.
However arch is already in use as a command on Unix: it prints the machine architecture (e.g. i686). It's kind of a waste of a word, but nevertheless it exists and is depended upon by some scripts. So the program can't be actually called arch. For a while it was called larch, and there were forks with different command names. Some people say that Arch is the design and tla is the implementation.
Now it has settled on tla, which is either Tom Lord's
Arch
, three letter acronym
, or doesn't stand for anything
at all.
The short story is that Arch
and tla
are interchangeable
when talking to people, but for computers you need to spell it
tla.
