+ * Representation of a process' environment variables.
+ *
+ * The environment is a map that establishes an unidirectional
+ * association between variable names and their values and is
+ * represented by a string to string map.
+ *
+ * Variables may be defined to the empty string. Be aware that doing so
+ * is not portable: POSIX systems will treat such variables as being
+ * defined to the empty value, but Windows systems are not able to
+ * distinguish them from undefined variables.
+ *
+ * Neither POSIX nor Windows systems support a variable with no name.
+ *
+ * It is worthy to note that the environment is sorted alphabetically.
+ * This is provided for-free by the map container used to implement this
+ * type, and this behavior is required by Windows systems.
