+// Breakpad test application for Linux. When run, it generates one on-demand
+// minidump and then crashes, which should generate an on-crash minidump.
+// dump_syms can be used to extract symbol information for use in processing.
+
+// To build:
+// g++ -g -o linux_test_app -I ../../ -L../../client/linux linux_test_app.cc \
+//   -lbreakpad
+// Add -m32 to build a 32-bit executable, or -m64 for a 64-bit one
+// (assuming your environment supports it). Replace -g with -gstabs+ to
+// generate an executable with STABS symbols (needs -m32), or -gdwarf-2 for one
+// with DWARF symbols (32- or 64-bit)
