See "hg archive". It does exactly that for you. Run "hg help archive".
It will also make tarballs and other archive formats.

Also see "hg blame". (Run "hg help blame" for usage info.)
For example, inside my "hg/css" repository I can say:
hg blame bin/set-x
and the output goes:
[hg/css]fleet*> hg blame bin/set-x
11359: # Trace execution of a command.
and so on the the end of the file. That tells me when those lines
of the file were last modified (by local changeset number). You
could pick a line in the file that you're interested in and look
at log entries for that.
For example, taking "11359" from the above listing, I can go:
[hg/css]fleet*> hg log -r 11359
user: Cameron Simpson <cs at zip.com.au>
date: Wed Mar 05 10:37:09 2014 +1100
set-x: add --date option to timestamp command start and end, upgrade option parsing logic
That is for the whole changeset, but it happens to affect just that one
Alternatively, although there may be many many changes, for some
files it is not so noisy. You might go:
hg log bin/set-x
to show only changes involving that particular file.
