#
# SYNOPSIS
#
# AX_PROG_DOTNETCORE_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
#
# DESCRIPTION
#
# Makes sure that .NET Core supports the version indicated. If true the
# shell commands in ACTION-IF-TRUE are executed. If not the shell commands
# in ACTION-IF-FALSE are run. The $dotnetcore_version variable will be
# filled with the detected version.
#
# This macro uses the $DOTNETCORE variable to perform the check. If
# $DOTNETCORE is not set prior to calling this macro, the macro will fail.
#
# Example:
#
# AC_PATH_PROG([DOTNETCORE],[dotnet])
# AC_PROG_DOTNETCORE_VERSION([1.0.2],[ ... ],[ ... ])
#
# Searches for .NET Core, then checks if at least version 1.0.2 is
# present.
