(** Gettext functions for OCaml virt tools.
The Common_gettext module provides gettext functions, or dummy
functions if ocaml-gettext was not available at configure time.
{b Note}: Don't translate debug strings, or strings which are
meant to be read/written only by machine.
There are two ways to translate constant strings in OCaml programs.
For ordinary strings, replace [["string"]] with [[s_"string"]]. Since
this is a function call to a function called [[s_]], you may have
to put parentheses around the expression.
For format strings, use:
{v
printf (f_"zeroing filesystem %s") filename;
v}
Note for format strings, the parentheses are almost always required,
and they just go around the [[(f_"string")]], {i not} around the other
arguments of the printf function.
At build time, a program parses the OCaml code into an abstract
syntax tree and statically determines all calls to the special
[[s_]] and [[f_]] functions, which means: (a) You can be very loose
with syntax, unlike ordinary xgettext, but (b) you cannot rename
these functions.
