#@417 Substitute environment variables referred to in STRING.
`$FOO' where FOO is an environment variable name means to substitute
the value of that variable.  The variable name should be terminated
with a character not a letter, digit or underscore; otherwise, enclose
the entire variable name in braces.  For instance, in `ab$cd-x',
`$cd' is treated as an environment variable.

Use `$$' to insert a single dollar sign.

#@894 Set the value of the environment variable named VARIABLE to VALUE.
VARIABLE should be a string.  VALUE is optional; if not provided or
nil, the environment variable VARIABLE will be removed.

Interactively, a prefix argument means to unset the variable, and
otherwise the current value (if any) of the variable appears at
the front of the history list when you type in the new value.
This function always replaces environment variables in the new
value when called interactively.

SUBSTITUTE-ENV-VARS, if non-nil, means to substitute environment
variables in VALUE with `substitute-env-vars', which see.
This is normally used only for interactive calls.

The return value is the new value of VARIABLE, or nil if
it was removed from the environment.

This function works by modifying `process-environment'.

As a special case, setting variable `TZ' calls `set-time-zone-rule' as
a side-effect.

#@478 Get the value of environment variable VARIABLE.
VARIABLE should be a string.  Value is nil if VARIABLE is undefined in
the environment.  Otherwise, value is a string.

If optional parameter FRAME is non-nil, then it should be a
frame.  This function will look up VARIABLE in its 'environment
parameter.

Otherwise, this function searches `process-environment' for
VARIABLE.  If it is not found there, then it continues the search
in the environment list of the selected frame.
