Unable to use with Emacs < 24.3

[Serghei Iakovlev]

From the README.md:

$EMACS_VERSION: The Emacs version to install. Supports any released version of GNU Emacs (tested with 24.1 and upwards), release candidates (e.g. 25.1-rc2) or the special value snapshot to clone the latest master from Emacs’ Git. Defaults to the latest stable release of GNU Emacs.

Well, readme says that "tested with 24.1 and upwards". I just tested this by adding in my .travis.yml versions as follows:

env:
  matrix:
+    - EMACS_VERSION=24.1
+    - EMACS_VERSION=24.2
     - EMACS_VERSION=24.3
     - EMACS_VERSION=24.4
     - EMACS_VERSION=24.5
     - EMACS_VERSION=25.1
     - EMACS_VERSION=25.2
     - EMACS_VERSION=snapshot

Output for Emacs 24.1:

Indeed. We could change the README to 24.2 and up.

Is there a point to testing for 24.1? That release is 5 years old now, and adding logic to grab GZ or XZ or BZ2 for this special case isn't worth it.

[Serghei Iakovlev]

As you can see there is issue with 24.2 too

[fmdkdd]

Oh right. What's the issue here exactly? The archive does not have the same hierarchy?

In any case, unless there's an easy fix to make these work, I would move to update the notes to state that we support only Emacs 24.3 and up.
