source: greenstone3/trunk/gs3-setup.sh@ 20984

Last change on this file since 20984 was 20984, checked in by davidb, 13 years ago

setup now looks for 'child' setup.bash files in the 'ext' folder and sources those as well if found (as is already done for GS2). Minor tweaks to improve readability of echo statements added also.
