+Although the author has not used Emacs for many years (apologies to
the Emacs fans out there), here is a quick hint to get you started. To
replace the leading spaces of every line in a file, use:
C<C-E<lt>> and C<C-E<gt>> to set the mark at the beginning and end of the
file respectively.
+Also, Stefan Kangas sent in the following tip about an alternate
+approach using the command C<indent-region> to redo the indentation
+for the currently selected region (adhering to indent rules in the
+current major mode). You can run the command by typing M-x indent-
+region or pressing the default keybinding C-M-\ in cperl-mode.
+Additional details can be found here:

the beauty of the MVC architecture is that very little database-specific
code is spread throughout the system (at least when MVC is "done
right"). Consequently, converting from one database to another is
features in each database for issues such as referential integrity and
field types/constraints.
