The Man Page gives me this info on the read/write/create capabilities:
EXIFTOOL(1)           User Contributed Perl Documentation          EXIFTOOL(1)
NAME
       exiftool - Read and write meta information in files
SYNOPSIS
       exiftool [OPTIONS] [-TAG...] [--TAG...] FILE...
       exiftool [OPTIONS] -TAG[+-<]=[VALUE]... FILE...
       exiftool [OPTIONS] -tagsFromFile SRCFILE [-SRCTAG[>DSTTAG]...] FILE...
       exiftool [ -ver | -list[w|f|wf|g[NUM]|d|x] ]
       For specific examples, see the EXAMPLES sections below.
DESCRIPTION
       A command-line interface to Image::ExifTool, used for reading and writ-
       ing meta information in image, audio and video files.  FILE is a source
       file name, directory name, or "-" for the standard input.  Information
       is read from the source file and output in readable form to the console
       (or written to an output text file with the -w option).
       To write or copy information, new values are specified with the
       -TAG=[VALUE] syntax or the -tagsFromFile or -geotag options.  This
       causes FILE to be rewritten, and by default the original file is pre-
       served with "_original" appended to the file name.  (Be sure to verify
       that the new file is OK before erasing the original.)  Once in write
       mode, exiftool will ignore any read-specific options.
       Below is a list of file types and meta information formats currently
       supported by ExifTool (r = read, w = write, c = create):
