libepoxy-dev 1.5.5-1build1 (armhf binary) in ubuntu impish

 It hides the complexity of dlopen(), dlsym(), glXGetProcAddress(),
 eglGetProcAddress(), etc. from the app developer, with very little
 knowledge needed on their part. They get to read GL specs and write
 code using undecorated function names like glCompileShader().
 .
 This package contains the development headers for the library found in
 libepoxy0. Non-developers likely have little use for this package.
