Standard flags

Each act subcommand takes the following command-line flags:

Controlling output

• -no-warnings: disables the printing of warnings generated by act. (Errors, as well as warnings generated by external programs, remain enabled.)
• -verbose: generally increases the verbosity of act's output (without this, act prefers to be fairly quiet when everything is going OK). Different commands interpret this in different ways.

Overriding defaults

• -spec FILE: tells act to read its [configuration] from FILE. (It defaults to compiler.spec.)

Miscellaneous

• -help: prints (autogenerated) command-line help.
