LineTally is a freeware application designed to allow programmers to count the number of lines in their source code. It supports about 61 languages. An unlimited number of user defined languages can be defined as well. It can tell the programmer how many code lines, comment lines, mixed lines (code and comments on the same line), blank lines, and total lines that were found as well as their respective percentages.
Version 1.7 adds more languages and minor changes.
