 This script analyses Raman spectra of Carbonaceous Material, by fitting Lorentzian distributions
 to the G, D1, D2, D3 and D4 peaks, as well as correcting for a linear background.
 The input is taken from a series of `x y` text files as produced by a Renishaw Raman spectrometer using
 Wire software, or from other Raman spectrometry software. 
 
 Proprietary .wxd files can be converted into two-column space-separated text files 
-(wavenumber intensity) using the "Wire Batch Convert" program. 
+(wavenumber intensity) using the "Wire Batch Convert" program provided by Renishaw. 
 
 The text files should be contained within one single folder, or grouped into sub-folders.
