GUI search and replace with Perl plus other file and folder tools

Eluent Tools is a collection of file and folder tools for Windows. The tools include Eluent Replace, a GUI-based, interactive, multi-pattern, multi-file search and replace program that uses Perl regular expressions and supports Perl scripting; Eluent Find, a file contents searcher and viewer that supports a variety of regular expression dialects, including Perl; Eluent Attrib, a program which modifies file and folder attributes, including the Compressed and Encrypted attributes under Windows NT/2000/XP; Eluent Dir, a flexible file finder based on Path Plans, the common method for specifying file searches in Eluent Tools; Eluent EOL, a program for converting text files between DOS/Windows, Macintosh, and Unix formats; Eluent Tab, a program for converting tabs to spaces and vice versa in text files; and Eluent Touch, a program for modifying file and folder timestamps. The tools were designed to work well as graphical desktop applications launched from the Start Menu and Windows Explorer context menus and as non-interactive command line tools, and they support a number of features related to Microsoft Visual C++ 5 and 6 and Visual Studio .NET, where they make excellent additions to the Tools menu. In particular, Eluent Replace provides Visual C++ with powerful Replace in Files capabilities, and Eluent Find is more flexible than Find in Files. The tools share a common interface for specifying files and folders to process, and settings can be saved in Path Plans for later use. Path Plans provide very flexible filtering options and support a rich variety of sources besides the usual directory search, such as response files, projects currently open in Visual C++ and VS.NET, and the Windows Indexing Service.
