/*
* plotfile.c
*
* plotfile filein rootout outputtype
*
* filein: input data file (e.g., gplotdata.example)
* rootout: root name of generated gnuplot data and cmd files
* outputtype: one of {PNG, PS, EPS, X11}
*
* plotfile is a program that allows you to use gnuplot with
* input from a single data file, in a simplified format.
*
* See the file gplotdata.example to see how to enter data for
* multiple plots in different plot styles.
*
* The format specifications for the input file are as follows:
*
* ------------------
* Header Information
* ------------------
*
* All lines starting with '%' are comments and are ignored
* All blank lines are ignored
* The header information is optional. It must be followed
* by a line beginning with '&' to signal the beginning of the data.
*
* If header plotinfo lines exist, the first three must be
* title
* xaxis label
* yaxis label
* These all default to null strings.
*
* Optionally after that, the individual plots can be
* labelled and the drawing method specified. This is
* done by specifying:
* number of plots
* title for plot 1
* drawing style for plot 1
* title for plot 1
* drawing style for plot 1
* ...
*
* Default for this is to have the individual plots untitled
* and to use LINES for each plot. The drawing styles allowed
* must be chosen from the set:
* {LINES, POINTS, IMPULSES, LINESPOINTS, DOTS}
*
* ------------------
* Data Information
* ------------------
*
* Use '&' at the beginning of a line as a control character.
* The first '&' signals that the data is to start
* Subsequent '&' are separators between data for different plots.
* This way, multiple plots can be drawn on the same output graph.
*
* All blank lines or lines starting with '%' are ignored.
*
* Data in file can have either one or two numbers per line.
* If there is one number, it is assumed to be the "y" value,
* and the "x" value is taken to be the line number, starting with 1.
*
* All characters other than the digits 0-9, '+', '-' and '.' are ignored,
* (with the exception that '%' and '&' have a special meaning when
* at the beginning of a line).
