Ftp the build and configuration summary (is it called build.txt?) to ftp://pike.ida.liu.se/incoming/ (upload only; friendly site admins are standing by). See some old release for filename conventions. Examples:
http://pike.ida.liu.se/download/pub/pike/all/7.6.6/
Pike-v7.6.6-Linux-2.4.20-28.8-i686 Pike-v7.6.6-Linux-2.4.20-28.8-i686.txt Pike-v7.6.6-Linux-2.4.22-ppc Pike-v7.6.6-Linux-2.4.22-ppc.txt Pike-v7.6.6-SunOS-5.9-sun4u Pike-v7.6.6-SunOS-5.9-sun4u.txt Pike-v7.6.6-doc.tar.gz Pike-v7.6.6.tar.gz
where the .txt files are the renamed configuration summary. (Failing to rename them probably risks overwriting the build info of others.)
