 .SS Comparison Conditional Directives
-           
+
+There are two Comparison Conditionals:
+
+.nf
+    .if string1 == string2   # True if string1 and string2 are identical
+    .if string1 != string2   # True if stringa and string2 are different
+.fi
+
+As a general matter, you can put literal strings on both sides of such a
+test, but the real value of these tests comes when you use variable
+references within the tested strings.  In this case, the value of the
+variable
+.B does matter.
+It is the variable's value that is replaced in the string to test for
+equality or inequality:
+
+.nf
+    MyName = Tconfpy
+    
+    .if [MyName] == Tconfpy
+         MyAge = 100.1
+
+    .else
+         MyAge = Unknown
+
+    .fi

+These are particularly useful when used in combination with the \*(TC
+Predefinded Variable or environment variables.  You can build configurations
+that "sense" what system is currently running and "adapt" accordingly:

+.nf

+
+    .if [.OSNAME] == FreeBSD
+        files = [$HOME]/[AppFiles]
