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)
