+ Adjusting the configuration to various contexts.
+
+ In most of the cases, people want their Emacs to behave the same on
+ all their machines, so their configuration should be the same, no
+ matter whether it's GNU/Linux or not, under X11 or on a tty, with one
+ version of Emacs or another, ...
+
+ What can happen, tho, is that depending on the circumstance some
+ features may or may not be available. In that case just prepend each
+ such customization with a little test that ensures that the feature
+ can be used. The best tests are usually checking that the feature is
+ available, rather than checking what kind of environment is
+ being used.
+
+ @example
+ (if (fboundp 'blinking-cursor-mode)
+ (blinking-cursor-mode 0))
+ @end example
+
+ @example
+ (if (boundp 'coding-category-utf-8)
+ (set-coding-priority '(coding-category-utf-8)))
+ @end example
+
+ @example
+ (require 'cl) ; To define `ignore-errors'.
+ (ignore-errors (set-face-background 'region "grey75"))
+ @end example
+
+ Note also that a @code{setq} on a variable which does not exist is
+ generally harmless, so those usually do not need to be made
+ conditional on any kind of test.
