|
26 ## Recompile all .elc files that need recompilation. Requires a
|
|
108
|
27 ## working version of "xemacs". Correctly handles the case where the
|
|
|
28 ## .elc files are missing; thus you can execute "rm lisp/*/*.elc"
|
|
70
|
29 ## before running this script. Run this from the parent of the
|
|
108
|
30 ## "lisp" directory, or another nearby directory.
