well finaly, if nothing happened in one of the lines, then the two lines
become the same, when merging back into one line. and the two lines
overlay each other. That is what i saw during playing with git-merge,
git-pull and git-reset.. ok.

its just the thought "cool, it looks like there at the git repo"... just
to realize "ok, that happens, when i merge two trees.

well the namespace of the references confused me, before i realized,
that HEAD finally points to an sha1sum (which symbolizes a certain commit)

mh.. I use pull if i want to get an external development tree, right? I
still search for a possibility to replace the svn:externals, which were
quite handy some times.

lets imagine, i want to reuse work i did in another repository, then I
can easily pull from that repository, which my work i want to reuse is
stored at... i see... i just will have to pull frequently.... and hope
there is no conflict between some files.


once more... thank you all and good work.
