This program is heavily inspired by gofmt and re-uses a lot of code and
style from that program.
Usage
nginxfmt [flags] [path ...]
Flags are:
-l
Do not print reformatted configuration to standard output.
If a file's formatting is different from nginxfmt's, print its name
to standard output.
-w
Do not print reformatted configuration to standard output.
If a file's formatting is different from nginxfmt's, overwrite it with
nginxfmt's version.
The paths can be a list of file names and/or directories. If a directory is
given, it is assumed all files in the directory are Nginx configuration files
for processing.
