+[[issues]]
+ISSUES
+------
+Problems related to timestamps:
+
+ * If timestamps of commits in the cvs repository are not stable enough
+ to be used for ordering commits changes may show up in the wrong
+ order.
+ * If any files were ever "cvs import"ed more than once (e.g., import of
+ more than one vendor release) the HEAD contains the wrong content.
+ * If the timestamp order of different files cross the revision order
+ within the commit matching time window the order of commits may be
+ wrong.
+
+Problems related to branches:
+
+ * Branches on which no commits have been made are not imported.
+ * All files from the branching point are added to a branch even if
+ never added in cvs.
+ * This applies to files added to the source branch *after* a daughter
+ branch was created: if previously no commit was made on the daughter
+ branch they will erroneously be added to the daughter branch in git.
+
+Problems related to tags:
+
+* Multiple tags on the same revision are not imported.
+
+If you suspect that any of these issues may apply to the repository you
+want to import consider using these alternative tools which proved to be
+more stable in practice:
+
+* cvs2git (part of cvs2svn), `http://cvs2svn.tigris.org`
+* parsecvs, `http://cgit.freedesktop.org/~keithp/parsecvs`
