 Of course, this means that your build system needs to become more
 complicated.  If you use \man{make}{1}, then something like
 \begin{prog}

 The following is a simple Sod input file.

 \end{prog}
 Save it as @"greeter.sod", and run
 \begin{prog}
-sod --gc --gh greeter
+  sod --gc --gh greeter
 \end{prog}
 This will create files @"greeter.c" and @"greeter.h" in the current
 directory.  Here's how we might use such a simple thing.
 \begin{prog}
-\#include "greeter.h" \\
-\\
-int main(void) \\
-\{ \\ \ind
-  SOD_DECL(Greeter, g); \\
-  \\
-  Greeter_greet(g, stdout); \\
-  return (0); \- \\
-\}
+  \#include "greeter.h"
+  \\+
+  int main(void) \\
+  \{ \\ \ind
+    SOD_DECL(Greeter, g);
+    \\+
+    Greeter_greet(g, stdout); \\
+    return (0); \- \\
+  \}
 \end{prog}
 Compare this to the traditional
 \begin{prog}
-\#include <stdio.h> \\
-\\
-int main(void) \\ \ind
-  \{ fputs("Hello, world@\\n", stdout); return (0); \}
+  \#include <stdio.h>
+  \\+
+  int main(void) \\ \ind
+    \{ fputs("Hello, world@\\n", stdout); return (0); \}
 \end{prog}
 and I'm sure you'll appreciate the benefits of using Sod already -- mostly to
 do with finger exercise.  Trust me, it gets more useful.
