$(P Phobos is the standard runtime library that comes with the D language
compiler.)

$(P Generally, the $(D std) namespace is used for the main modules in the
Phobos standard library. The $(D etc) namespace is used for external C/C++
library bindings. The $(D core) namespace is used for low-level D runtime
functions.)

$(P The following table is a quick reference guide for which Phobos modules to
use for a given category of functionality. Note that some modules may appear in
more than one category, as some Phobos modules are quite generic and can be
applied in a variety of situations.)
