A variable is defined as an identifier following a \$
symbol. An identifier is either a sequence of alphanumeric characters
following an alphabetic character, or an identifier enclosed in
matching parens or brackets. Hence \$ident,
\$(ident), or \${ident} are variables.
A variable can be bound either in the system environment or in the
Htmlc compiler's environment. System bound variables are enclosed by
< and >. Hence,
\$<ident> is a reference to the system variable
ident.
All other variables are compiler's environment bound.
\$<variable>
<!--#echo var="\$<variable>"-->
LE_HTMLC = $\$variable,
\$(variable), or \${variable}.
