|
|
|
9 ## Recompile all .elc files that need recompilation. Requires a
|
|
|
10 ## working version of 'xemacs'. Correctly handles the case where the
|
|
|
11 ## .elc files are missing; thus you can execute 'rm lisp/*/*.elc'
|
|
|
12 ## before running this script. Run this from the parent of the
|
|
|
13 ## `lisp' directory, or another nearby directory.
