# startup script for smalltalk
# actually, simply calls stx, passing all arguments.
#
# In previous versions, smalltalk used to be the executable itself.
# This lead to problems on systems, where things like LD_LIBRARY_PATH
# should be set in advance.
# Now, here is a place to do such things ...
#
# -x name specifies an explicit executable
# to avoid executing another stx from some directory along the PATH
# (i.e to force use: ./smalltalk -x ./stx)
#
# -X name specifies an explicit path to the stx executable
# to avoid executing another stx from some directory along the PATH
# (i.e to force use: ./smalltalk -X .)
# [almost the same as above]
#
# -ldd show ldd-output (to debug, which libs are loaded)
#
# all other args go to stx & the user classes
#
