svn commit: r1936953 - subversion/trunk

Author: lyalyakin
Date: Fri Aug  7 09:51:54 2026
New Revision: 1936953

Log:
Add LZ4 to the I.B section of the INSTALL guide and mark it as REQUIRED in
I.C.20.

  (I.B: Dependency Overview): Add a missing entry for LZ4.
  (I.C: Dependencies in Detail): Mark LZ4 as 'REQUIRED', not 'OPTIONAL':
   [[[
   configure: error: Subversion requires LZ4 >= r129, or use --with-lz4=internal
   ]]]
   Even though SVN sources have a copy of LZ4, it's still a required
   dependency.
