This specifies 
	p = TEX prefix
	q = TEX postfix
	c = TEX command
Only the prefix is likely to need changing.
One possibility is to replace the string here by operations that open
a TEX header file and return its contents as the prefix.
Or concatenate it with part of the prefix.

For example:
		f = open("myheader.tex", "r")
		p = f.read()
		f.close()
