$out/manifest.nix rather than as an ATerm.
(Hm, I thought I committed this two days ago...)

collision.
|
|
user environment collission between two packages due to overlapping
file names, then a package with a higher priority will overwrite the
symlinks of a package with a lower priority. E.g.,
$ nix-env --set-flag priority 5 gcc
$ nix-env --set-flag priority 10 binutils
gives gcc a higher priority than binutils (higher number = lower
priority).

allow switching between them (NIX-80).
Example: two versions of Pan:
$ nix-env -q pan
pan-0.128
pan-0.14.2.91
$ readlink $(which pan)
/nix/store/l38jrbilw269drpjkx7kinhrxj6fjh59-pan-0.14.2.91/bin/pan
At most one of them can be active any given time. Assuming than
0.14.2.91 is active, you can active 0.128 as follows:
$ nix-env --set-flag active false pan-0.14.2.91
$ nix-env --set-flag active true pan-0.128
$ readlink $(which pan)
/nix/store/nziqwnlzy7xl385kglxhg75pfl5i936n-pan-0.128/bin/pan
More flags to follow.

for packages that should be propagated to the user environment.

*after* the packages that have been explicitly installed, and
collisions are ignored.

representation instead of an ATerm.
* Indent XML output.

Maybe this is a bad idea.

The expression `with E1; E2' evaluates to E2 with all bindings in
the attribute set E1 substituted. E.g.,
with {x = 123;}; x
evaluates to 123. That is, the attribute set E1 is in scope in E2.
This is particularly useful when importing files containing lots
definitions. E.g., instead of
let {
inherit (import ./foo.nix) a b c d e f;
body = ... a ... f ...;
}
we can now say
with import ./foo.nix;
... a ... f ...
I.e., we don't have to say what variables should be brought into scope.

efficient by creating only a single symlink to entire directory
trees unless a collission occurs.
