+# We use the release tarball from GitHub instead of the sources in the repo because:
+#  - igraph will not compile from the git sources unless there is an actual git repository to back it. This is because it detects the version from git tags. The release tarball has the version hard-coded.
+#  - The release tarball contains pre-generated parser sources, which eliminates the dependency on bison/flex.
