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 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.
