--file [FILE ...]
Specifies the compiled JavaScript build file to analyze.
--file1 [FILE1 ...]

--list-unaccounted LIST_UNACCOUNTED
Pass --list-unaccounted=0 to skip listing a summary entry of un-
accounted content
--dump-unaccounted-larger-than DUMP_UNACCOUNTED_LARGER_THAN
If an integer value >= 0 is specified, all unaccounted strings
of content longer than the given value will be printed out to
the console. (Note that it is common to have several unaccounted
blocks, this is provided for curiosity/debugging/optimization
ideas)
--only-unique-1
If two data sets are specified, prints out only the symbols that
are present in set 1, but not in set 2
--only-unique-2
If two data sets are specified, prints out only the symbols that
are present in set 2, but not in set 1
--only-common
If two data sets are specified, prints out only the symbols that
are common to both data sets
--only-changes
If two data sets are specified, prints out only the symbols that

--filter-size FILTER_SIZE
Only prints out information about symbols that are (or were)
larger than the given amount of bytes.
--sort SORT
Specifies the data column to sort output by. Possible values

demangled
--print-format PRINT_FORMAT
Specifies the naming format for the symbols. Possible options
are one of: m, u, d, du, dm, um, dum. Here "m" denotes minified,
"u" denotes unminified, and "d" denotes demangled. Specify any
combination of the characters in upper case to print out func-
