Internal Program Version: stackusage v1.21 (The man files)

Stackusage measures stack usage in Linux applications (main thread and native
pthread child threads). The measured stack utilization data can be used to
adjust the stack size allocation to provide desired margin for child threads.
This is primarily useful for applications and libraries designed to work in
resource-constrained environments (such as embedded systems).
