The syntax for dcpomatic2_map is:

dcpomatic2_map [OPTION] <cpl-file|ID> [<cpl-file|ID> ...]

Each <cpl-file|ID> is either a filename or a UUID of a CPL that you want to include in the output DCP.

dcpomatic2_map will search for CPLs (when given by ID) and other required assets in directories that you specify with the -d or --assets-dir option.

A new DCP will be created in the directory specified by -o or --output which contains the CPLs you specify, along with the required assets and other ancillary files (PKL, AssetMap etc.)

By default, all the required assets will be copied into the new DCP. You can change this behaviour by passing -l or --hard-link to hard-link the assets (on filesystems and platforms that support this) or -s or --soft-link to soft-link the assets.

Passing -r or --rename will rename asset files to match DCP-o-matic's configured naming scheme.

--config <dir> can be used to specify a directory containing the DCP-o-matic configuration to use for the DCP naming scheme, creator/issuer metadata, signer chain and so on.
