 +==== defenv ====
 +
 +Preprocessor directive to define an ID to the value of an environment variable with the name ENVVAR.
 +
 +<code c>
 +#!defenv ID=ENVVAR
 +</code>
 +
 +It can also be just **$!defenv ENVVAR** and the defined ID is the ENVVAR name.
 +
 +Example:
 +
 +<code c>
 +#!defenv SHELL
 +</code>
 +
 +If environment variable $SHELL is '/bin/bash', then it is like:
 +
 +<code c>
 +#!define SHELL /bin/bash
 +</code>
 +
 +Full expression variant:
 +
 +<code c>
 +#!defenv ENVSHELL=SHELL
 +</code>
 +
 +Then it is like:
 +
 +<code c>
 +#!define ENVSHELL /bin/bash
 +</code>
 +
 +It is a simplified alternative of using **#!substdef** with **$env(NAME)** in the replacement part.
