+(the whole file, mail message, and so on). @option{-decompress} option
+tries to zlib-decompress the data from plain packet (useful for mail
+packets).

+
+Reassemble @ref{Chunked, chunked file} after @ref{nncp-toss, tossing}.
+
+When called with @option{FILE} option, this command will reassemble only
+it. When called with @option{-node} option, this command will try to
+reassemble all @file{.nncp.meta} files found in @option{NODE}'s
+@ref{CfgIncoming, incoming} directory. When called with @option{-all}
+option, then cycle through all known nodes to do the same.
+
+Reassembling process does the following:
+
+@enumerate
+@item Parses @ref{Chunked, @file{.nncp.meta}} file.
+@item Checks existence and size of every @file{.nncp.chunkXXX}.
+@item Verifies integrity of every chunk.
+@item Concatenates all chunks, simultaneously removing them from filesystem.
+@end enumerate
+
+That process reads the whole data twice. Be sure to have free disk
+space for at least one chunk. Decrypted chunk files as a rule are saved
+in pseudo-random order, so removing them during reassembly process will
+likely lead to filesystem fragmentation. Reassembly process on
+filesystems with deduplication capability should be rather lightweight.
+
+If @option{-dryrun} option is specified, then only existence and
+integrity checking are performed.
+
+If @option{-keep} option is specified, then no
+@file{.nncp.meta}/@file{.nncp.chunkXXX} files are deleted during
+reassembly process.
+
+@option{-stdout} option outputs reassembled file to stdout, instead of
+saving to temporary file with renaming after. This could be useful for
+reassembling on separate filesystem to lower fragmentation effect,
+and/or separate storage device for higher performance.
+
+@option{-dump} option prints meta-file contents in human-friendly form.
+It is useful mainly for debugging purposes. For example:
+@verbatim
+Original filename: testfile
+File size: 3.8 MiB (3987795 bytes)
+Chunk size: 1.0 MiB (1048576 bytes)
+Number of chunks: 4

+Remove specified packet (Base32 name) in @option{NODE}'s queues. This
+command is useful when you want to remove the packet that is failing to
+be processed.
