If you face challenges like these ...

• The latest version introduced a bug and you need to retrieve an older, working version
• A user has a problem with an earlier version and you must duplicate it
• Changes made by one programmer are lost when the file is overwritten by another programmer working on the same file
• Bug fixes that were made in the old release need to be migrated into the new release
• Improvements to the standard version need to be added to customized versions. (This one can be a real nightmare!)

• Show the differences between two disk files or between two versions of a single file
• Shows you what has changed within the lines, as well as identifying which lines have changed.
• Instant, one-click compare between a New version and its predecessor during Update (check-in)

• File-oriented ("normal") mode. Lets you use wild-cards and/or file-lists to specify files to be managed by TLIB.
• Native project mode. Both 16-bit and 32-bit versions of TLIB let you "open" your compiler's or editor's native project file directly, avoiding the need to use wild-card specifications or file-lists. Just click the "Mode" button to switch between Native Project mode and normal (file-oriented) mode. Many compilers, editors, and other tools are supported, plus Web sites and plain file lists.
• API mode. TLIB supports three Public APIs (and a fourth is coming). They are used by add-in modules and other products that interface to TLIB for Windows. Two APIs interface to the TLIB for Windows GUI. We also support a lower-level call-interface API directly to the TLIB DLL engine, bypassing the GUI front end.
