 591 <h2 id="_description">DESCRIPTION</h2>
 592 <div class="sectionbody">
 593 <div class="paragraph"><p>Imports a project from one or more Arch repositories. It will follow branches
 594 and repositories within the namespaces defined by the &lt;archive/branch&gt;
 595 parameters supplied. If it cannot find the remote branch a merge comes from
 596 it will just import it as a regular commit. If it can find it, it will mark it
 597 as a merge whenever possible (see discussion below).</p></div>
 598 <div class="paragraph"><p>The script expects you to provide the key roots where it can start the import
 599 from an <em>initial import</em> or <em>tag</em> type of Arch commit. It will follow and
 600 import new branches within the provided roots.</p></div>
 601 <div class="paragraph"><p>It expects to be dealing with one project only. If it sees
 602 branches that have different roots, it will refuse to run. In that case,
 603 edit your &lt;archive/branch&gt; parameters to define clearly the scope of the
 604 import.</p></div>
 605 <div class="paragraph"><p><em>git archimport</em> uses <tt>tla</tt> extensively in the background to access the
 606 Arch repository.
 607 Make sure you have a recent version of <tt>tla</tt> available in the path. <tt>tla</tt> must
 608 know about the repositories you pass to <em>git archimport</em>.</p></div>
 609 <div class="paragraph"><p>For the initial import, <em>git archimport</em> expects to find itself in an empty
 610 directory. To follow the development of a project that uses Arch, rerun
 611 <em>git archimport</em> with the same parameters as the initial import to perform
 612 incremental imports.</p></div>
 613 <div class="paragraph"><p>While <em>git archimport</em> will try to create sensible branch names for the
 614 archives that it imports, it is also possible to specify git branch names
 615 manually.  To do so, write a git branch name after each &lt;archive/branch&gt;
 616 parameter, separated by a colon.  This way, you can shorten the Arch
 617 branch names and convert Arch jargon to git jargon, for example mapping a
 618 "PROJECT&#45;&#45;devo&#45;&#45;VERSION" branch to "master".</p></div>
 619 <div class="paragraph"><p>Associating multiple Arch branches to one git branch is possible; the
 620 result will make the most sense only if no commits are made to the first
 621 branch, after the second branch is created.  Still, this is useful to
 622 convert Arch repositories that had been rotated periodically.</p></div>
 623 </div>
 624 <h2 id="_merges">MERGES</h2>
 625 <div class="sectionbody">
 626 <div class="paragraph"><p>Patch merge data from Arch is used to mark merges in git as well. git
 627 does not care much about tracking patches, and only considers a merge when a
 628 branch incorporates all the commits since the point they forked. The end result
 629 is that git will have a good idea of how far branches have diverged. So the
 630 import process does lose some patch-trading metadata.</p></div>
 631 <div class="paragraph"><p>Fortunately, when you try and merge branches imported from Arch,
 632 git will find a good merge base, and it has a good chance of identifying
 633 patches that have been traded out-of-sequence between the branches.</p></div>

 668         Use the fast patchset import strategy.  This can be significantly
 669         faster for large trees, but cannot handle directory renames or
 670         permissions changes.  The default strategy is slow and safe.

 678         Use this for compatibility with old-style branch names used by
 679         earlier versions of <em>git archimport</em>.  Old-style branch names
 680         were category&#45;&#45;branch, whereas new-style branch names are
 681         archive,category&#45;&#45;branch&#45;&#45;version.  In both cases, names given
 682         on the command-line will override the automatically-generated
 683         ones.
