This post made me worry for the first time about one project of
mine (ciforth). It started in 2000 with an msdos assembler file,
and after several hundreds version it has accumulated doc's and test's
and is now usable on linux, windows whatnot.

Since 2000 the cvs style archive has grown to 2 megabyte,
for a current version of 400 kbyte. I kept the smallest of changes,
and at times was very happy I did.

Bottom line, the grow of a source archive cannot keep up
with LAN and Internet speeds and hard disk sizes.
