+So many packages, so many source files! The @command{guix edit} command
+facilitates the life of packagers by pointing their editor at the source
+file containing the definition of the specified packages. For instance:
+
+@example
+guix edit gcc-4.8 vim
+@end example

+@noindent
+launches the program specified in the @code{EDITOR} environment variable
+to edit the recipe of GCC@tie{}4.8.4 and that of Vim.
