# @DESCRIPTION:
# The dotnet eclass contains common environment settings that are useful for
# dotnet packages.  Currently, it 
# exports MONO_SHARED_DIR and
# sets LC_ALL in order to prevent errors during compilation of dotnet packages.

# Building mono, nant and many other dotnet packages is known to fail if LC_ALL

# build with LC_ALL=C (see bugs #146424, #149817)
