+﻿The location of source files for Serbian spelling dictionary were downloaded
+from 
+https://github.com/LibreOffice/dictionaries/tree/master/sr
+(Serbian Spelling and Hyphenation for LibreOffice).
+
+Here is the content of original README file from the repository:
+
+	"LibreOffice Spelling and Hyphenation
+	extension package for Serbian (Cyrillic and Latin)
+	
+	This extension package includes the Hunspell dictionary and Hyphen
+	hyphenation patterns for the Serbian language adapted for usage in
+	LibreOffice.
+	
+	Serbian spelling dictionary is developed by Milutin Smiljanic
+	<msmiljanic.gm@gmail.com> and is released under GNU LGPL version 3 or
+	later / MPL version 2 or later / GNU GPL version 3 or later, giving
+	you the choice of one of the three sets of free software licensing
+	terms.
+	
+	Serbian hyphenation patterns are derived from the official TeX
+	patterns for Serbocroatian language (Cyrillic and Latin) created by
+	Dejan Muhamedagić, version 2.02 from 22 June 2008 adopted for usage
+	with Hyphen hyphenation library and released under GNU LGPL version
+	2.1 or later."
+
+
+This dictionary used to create Vim spl file is the result of merging the two
+LibreOffice dictionaries, for cyrillic and latin script.
+
+The merge was accomplished by concatenating two .dic files, removing 1061
+duplicates using the fixdup Vim script and updating the word count.
+
+In both affix files each SFX (and two PFX) directive had to be appended with
+the . at the end of the line. KEY and WORDCHAR directives were removed, and
+MIDWORD was added.  Each SFX block is the union of corresponding blocks from
+sr.aff and sr-Latn.aff.  Header line of each block was updated to the new
+count (2 times the value from the corresponding block in the input affix
+file).
