 .SH "JOB FILE FORMAT"
-Job files are in `ini' format. They consist of one or more
-job definitions, which begin with a job name in square brackets and
-extend to the next job name.  The job name can be any ASCII string
-except `global', which has a special meaning.  Following the job name is
-a sequence of zero or more parameters, one per line, that define the
-behavior of the job.  Any line starting with a `;' or `#' character is
-considered a comment and ignored.
-.P
-If \fIjobfile\fR is specified as `-', the job file will be read from
-standard input.
-.SS "Global Section"
-The global section contains default parameters for jobs specified in the
-job file.  A job is only affected by global sections residing above it,
-and there may be any number of global sections.  Specific job definitions
-may override any parameter set in global sections.

+Any parameters following the options will be assumed to be job files, unless
+they match a job file parameter. Multiple job files can be listed and each job
+file will be regarded as a separate group. Fio will `stonewall` execution
+between each group.
+
+Fio accepts one or more job files describing what it is
+supposed to do. The job file format is the classic ini file, where the names
+enclosed in [] brackets define the job name. You are free to use any ASCII name
+you want, except *global* which has special meaning. Following the job name is
+a sequence of zero or more parameters, one per line, that define the behavior of
+the job. If the first character in a line is a ';' or a '#', the entire line is
+discarded as a comment.
+
+A *global* section sets defaults for the jobs described in that file. A job may
+override a *global* section parameter, and a job file may even have several
+*global* sections if so desired. A job is only affected by a *global* section
+residing above it.
+
+The \-\-cmdhelp option also lists all options. If used with an `option`
+argument, \-\-cmdhelp will detail the given `option`.

-Boolean: a true or false value. `0' denotes false, `1' denotes true.

-Integer range: a range of integers specified in the format

+Integer range with suffix. Allows value range to be given, such as
