Zsh and Prezto files don't always reside in `~/`. Instead, they have
a more spec compliant location (`${ZDOTDIR:-$HOME}/`). Make them
unambiguous in the documentation. Likewise, for `$GNUPGHOME`.
Further, add instruction for optionally setting up Prezto in
`$XDG_CONFIG_HOME`.
While at this, also add clarification on relative ordering of some of
the modules, apply more formatting tweaks and doc improvements.
General purpose reformating and rewording in (a few places). This should
also make markdown linting happier.
Prefer back-ticks wherever useful and use `console` for code blocks to
be executed on terminal.
Also, update references links wherever possible (including update from
'http://' to 'https://').
`brew cleanup --force` produces the following error message: `Error: invalid option: --force`. I can't seem to find any record of this being a valid option for the cleanup command, so either it was deprecated in the stone age or it was a simple mistake. However, there is a `--force` option available for `brew uninstall`, but that's a dicey thing to alias.
- Add missing documentation for options and environment variables
- Rearrange definition and documentation of 'Options', 'Variables'
and 'Aliases' in a consistent order
Homebrew has deprecated `brew cask cleanup` and `brew cask search` in favor
of `brew cleanup` and `brew search` respectively. They will stop working on
2018-09-30. Further, `--outdated` has been removed.
We should eventually remove the related aliases, but for a while we keep
supporting them gracefully with deprecation warning.
The documentation has been removed from README.md, however.
Homebrew decided to not change the behaviour of `brew upgrade` so
`brew upgrade --all` is equivalent to `brew upgrade` without any other
arguments (so the `--all` is a no-op and can be removed).
