It does not appear to be usable as an application debugger, rather providing 
diagnostics about system call level behavioural anomalies, sampling system state 
with predefined interpreted AWK/C-like "D" scripts.

It appears to be a system call probe and event tracing and data collection tool, 
requiring a feature built in to recent Windows enabled, possibly built on Event 
Tracing for Windows, drivers, utilities, and matching OS symbols installed, 
offering command line initiated probe, event, executable, and user "D" script 
selection.

For cygwin executables, strace provides similar capabilities.
