1 zlib has been adapted slightly for use in rsync. Please don't bother
2 the zlib authors with problems related to the use of zlib in rsync as
3 any bugs are likely to be our fault and not theirs.
5 Specific changes that have been made to zlib for rsync include:
7 - add Z_INSERT_ONLY to allow for efficient history updating without
8 actually emitting any data. This is used to compress the matched
9 blocks that don't cross the wire, which gives better compression
10 ratios on the literal data.
12 - fixed a number of minor compilation issues. (redefinition of MAX and
13 other such trivial things)
15 - include rsync.h to ensure that we get a consistent set of includes
16 for all C code in rsync and to take advantage of autoconf
