// This function reads a .wav file and a text file containing marker locations (specified as frame indexes, one per line)
// and creates a new .wav file with embedded cue points for each location.  The code is standard, portable C.

Execstack is a great tool for learning and training on Linux. It is a program which sets, clears, or queries the executable stack flag of ELF binaries and shared libraries. When I was looking to install it I took me a bit to find which package to install it in.

You can install with :

Ubuntu

$ sudo apt-get install prelink

Arch Linux
