+<para>Normally, files ending in certain extensions (.exe, .com, .bat, .btm,
+.cmd) are assumed to be executable. Files whose first two characters begin
+with '#!' are also considered to be executable.
+The <literal>exec</literal> option is used to instruct Cygwin that the
+mounted file is "executable". If the <literal>exec</literal> option is used
+with a directory then all files in the directory are executable.
+This option allows other files to be marked as executable and avoids the
+overhead of opening each file to check for a '#!'. The
+<literal>cygexec</literal> option is very similar to <literal>exec</literal>,
+but also prevents Cygwin from setting up commands and environment variables
+for a normal Windows program, adding another small performance gain. The
+opposite of these options is the <literal>notexec</literal> option, which
+means that no files should be marked as executable under that mount point.

<para>The fifth and sixth field are ignored. They are
