DerBar is a simple, slightly-configurable status bar for monitoring key system and network parameters. It is modeled on older status-monitoring programs such as StatBar, WinBar, and InfoBar, but without the configuration options of those other programs; it is designed for compactness and compatibility, not for turning parts on and off. The few configuration options that are present, are accessed via the icon in the system tray. You can move DerBar anywhere you want, by grabbing it and dragging it around, and it will remember where you leave it next time it runs.
DerBar is compatible with all other programs and will not conflict with DirectX games, as each of the afore-mentioned tools would sometimes do. It works fine with WinXP and Vista+, but would likely not work on Win98 famiily due to UNICODE support.

DerBar is written in C++, using standard Windows library calls.
This application is built using the MinGW toolchain; I recommend the TDM distribution, to avoid certain issues with library accessibility. The makefile also requires certain Cygwin tools (rm, make, etc).
