Readlink usage not compatible with macOS

[p4tpr0]

Current use of command readlink in shell script code is not compatible with macOS:

• install fails
• execution fails

sample error upon execution: readlink: illegal option -- f usage: readlink [-n] [file ...] /usr/local/bin/sslmerge: line 57: ./../src/settings: No such file or directory /usr/local/bin/sslmerge: line 59: ./../src/helpers: No such file or directory /usr/local/bin/sslmerge: line 61: ./../src/__init__: No such file or directory /usr/local/bin/sslmerge: line 66: __main__: command not found /usr/local/bin/sslmerge: line 68: _exit_: command not found

Hi!

It's true that there is a problem with readlink on macos and freebsd.

1) I'll check what can be done with it. 2) I added information on what platform it works: Requirements

greadlink from coreutils package is alternative (tested on FreeBSD).

Also work on MacOS with greadlink from coreutils (installed via homebrew)

• replace for getopt(1) that supports GNU-style long options (pkg install getopt)
• also work on MacOS with greadlink from coreutils (installed via homebrew)
