// Dynamic library that pauses a short lived program during launch so that a
// debugger can attach to it. To use it, compile it on macOS:
//     clang -dynamiclib pause4debug.c -o pause4debug.dylib
// On Linux:
//     gcc -shared -fPIC pause4debug.c -o pause4debug.so
// To use it, make the dynamic linker inject it using DYLD_INSERT_LIBRARIES or
// LD_PRELOAD, depending on your platform. On macOS:
//     DYLD_INSERT_LIBRARIES=/path/to/pause4debug.dylib debugme
// On Linux,
//     LD_PRELOAD=/path/to/pause4debug.so debugme
