+substr.sty
+
+This package provides commands to deal with substrings in strings:
+Determine if a string contains a substring, count appearances of a
+substring in a string.
+
+
+The Description of the commands can be found in the file substr.sty.
+
+
+
+History of this package:
+
+The package arises from a posting of me in the newsgroup
+de.comp.text.tex in which I asked how to find out if a substring
+is included in a string. Heiko Oberdiek
+<oberdiek@ruf.uni-freiburg.de> posted the commands
+\IfSubStringInString and \IfCharInString and suggested to write a
+command which counts the appearances in a string. So, I wrote the
+commands \CountSubStrings and \setcountertoSubStrings.
+After I wrote this package I sent it to Heiko Oberdiek
+who improved and rewrote many parts of it.
