This allows to search in many files at once. Always look for the function name without the underscore in order to capture which is the correct function name underscoring (e.g. zscal_ vs zscal) defined in the system.

			In some systems compiled functions are stored in shared object files `.so` in ELF format. To find functions in these files use this program and option `readelf -Ws`; for example `readelf -Ws /usr/lib674/openmpi/lib/libscalapack.so`.
