Hi,
I am trying to package clojure-contrib for Debian and one of the
debian java packaging practices is that the build should not download
any external dependencies. All the dependencies should be debian
packages themselves.

Greetings,
Does Clojure have a notion of #line directive a la C/C++?
The reason for my asking is, I am generating Clojure code which is
embedded in TeX and I would like to see Clojure source code references
mapped to that original file.
If there is any built-in support in Clojure for ignoring b

Ok. I don't explain coorect why I want to have build-in ability to

In my study and job I very often use different spesific data

because it makes my code easilier to perception: work with data

Absolutely not! Having 'require' as an ordinary function (not a
macro) is important for code-generating code.

For now, yes, as ataggart showed. But I expect names in contrib will

And of course that should be (require '[clojure.contrib string io]) or
(require ['clojure.contrib 'string 'io]) so the symbols don't try to
get resolved.

And of course, that *does* work, thus my complaint was moot, and the
symbol non-resolution was probably what Stuart was so aghast about
(even though it wasn't my point).

Haha, I was just trying out traditional formatting with clojure and
had left it that way without noticing.
As for the lazy thing, I should have known that as it wasn't long ago
I was ready about laziness in the book I'm reading. Wrapping (dorun)
around the (for) loop has fixed it.

It occurs to me you could use 'some instead of nested if-lets:

(first (re-matches #".*(\.[0-9a-zA-Z]+)" line))])

A simplified version:
(some #(first (re-matches % line))
(some) definitely seems like the way to go. Now I've got to move onto
my next problem, which is totally the number of duplicate files and
the bytes they take up. I'm guessing at this point that something like
