The macro substitution text files of the HAM-ISIs were moved from:
/opt/rtcds/userapps/release/isi/common/medm/hamisi/ (now at revision 4499)
into:
/opt/rtcds/userapps/release/isi/h1/medm/hamisi/ (now at revision 4498)
The $(IFO) part of the name of those text files was removed to avoid redundancy: i.e. H1_isiham2_overview_macro.txt became: isiham2_overview_macro.txt
The sitemap was updated to reflect those changes. (now at revision 4500)
