# Usage:
# pegasus_arch_alternatives
# ( --list [pfx] |
# ( [ devel | test ] [ -64 ] [ -32 ] [ --remove ] [ --display ] )
# )
# no args : set up library and binary 'pegasus' alternatives
# --list : list 64/32-bit alternatives, with optional prefix pfx
# devel : set up the 'pegasus-devel' alternative
# test : set up the 'pegasus-test' alternative
# -64 : select 64-bit alternatives
# -32 : select 32-bit alternatives
# --remove : remove all pegasus alternatives
# --display: display the pegasus alternatives
