26.5.6 Variable Description

${vcs_info_msg_N_} (Note the trailing underscore)

Where N is an integer, e.g., vcs_info_msg_0_. These variables are the storage for the informational message the last vcs_info call has assembled. These are strongly connected to the formats, actionformats and nvcsformats styles described above. Those styles are lists. The first member of that list gets expanded into ${vcs_info_msg_0_}, the second into ${vcs_info_msg_1_} and the Nth into ${vcs_info_msg_N-1_}. (See the max-exports style above.)

All variables named VCS_INFO_* are for internal use only.
