 -c -fno-gnu-keywords -fexternal-templates   

This sample file shows 3 different options for the g++ compiler. You can make
the options as simple or as complex as you like. The rule is that only the
first line of this file is read by vpac. The line can extend over several
physical lines of a window providing there are no carriage returns[0xa]
NOTE:: at the end of each line of options leave a space [0x20] This is to
prevent the last word merging into the file name on the command line. In
this case there is a space after the word "-Wall","once" and "templates".
To check it out move the cursor to the end of any of the top three lines and
note that it points to a space and not a character. When editing the option
line just press the space bar at the end of the line then save the file.
The current options are just a sample. You must provide suitable options for
your compiler with ../include paths ect. Above are three seperate option lines.
Swapping lines can be achieved quicky by using the vim command dd and p to
delete the line then push it back in a different position. This rule of only
reading the first line of the file applies to the library options files also.
