28: ## Obvious flaws of this program:
29: ## Dieing on every error may be a little extreme. On the other hand,
30: ## how the heck am I supposed to know what absurd things the user
31: ## has done with their system before inflicting LON-CAPA on it?
32: ## The links to /etc/init.d for httpd and mysqld do not seem to work :(
33: ## The user is never informed of the log file (/tmp/loncapa_install.log).
34: ## It does not test the system at the end. Again, there are limits to
35: ## what nonsense we can put up with. Of course, we will have to
36: ## explain that to people at some point...
37: ## There is probably an overuse of elipses (...) in the comments.
