* Careful: order of argument flags does matter. For example,
*
- * git-checkout-index -a -f file.c
+ * git checkout-index -a -f file.c
*
* Will first check out all files listed in the cache (but not
* overwrite any old ones), and then force-checkout "file.c" a
* second time (ie that one _will_ overwrite any old contents
* with the same filename).
*
- * Also, just doing "git-checkout-index" does nothing. You probably
- * meant "git-checkout-index -a". And if you want to force it, you
- * want "git-checkout-index -f -a".

* Intuitiveness is not the goal here. Repeatability is. The

*
- * find . -name '*.h' -print0 | xargs -0 git-checkout-index -f --
+ * find . -name '*.h' -print0 | xargs -0 git checkout-index -f --
*
* or:
*
- * find . -name '*.h' -print0 | git-checkout-index -f -z --stdin
+ * find . -name '*.h' -print0 | git checkout-index -f -z --stdin
*
* which will force all existing *.h files to be replaced with
* their cached copies. If an empty command line implied "all",
