At its core, BK ReplaceEm is essentially a text search-and-replace program. However, unlike the search-replace functionality of a standard text editor, BK ReplaceEm is designed to operate on multiple files at once. And you need not only perform one search-replace operation per file -- you can setup a list of operations to perform. You can also specify a backup file for each file processed just in case the replace operation didn’t do exactly what you wanted.
