# test program for miniwget.c
# is usually invoked by "make check"
#
# This test program :
#  1 - launches a local HTTP server (minihttptestserver)
#  2 - uses testminiwget to retreive data from this server
#  3 - compares served and received data
#  4 - kills the local HTTP server and exits
#
# The script was tested and works with ksh, bash
# It fails to run with dash 0.5.5.1 because of "kill %1"
