# While I work use a variety of programs, below of some of my more commonly used
# programs that I have decided to support with aliases.
# Applications
#   java:       jv
#   tmux:       t
#   $EDITOR:    e
#   vim:        v
#   GnuPG:      gpg
#   blaze:      bz
#   borgcfg:    br
#   piper:      pi
#   pass:       ps
#   pastebin:   pb
#   pacman:     pm
#   codesearch: cs
#   git:        g
#   mercurial:  hg
#   aptitude:   apt
#   chrome:     c
#   elixir:     ex
#   haskell:    hk
#   wifi:       wf
#   piper:      pp
#   g4:         pp
#   g4d:        pp
#   cci:        circleci
#
# Below are some common modifiers or flags that programs support.
# Supported qualifiers:
#   hidden:      h
#   ignore-case: i
#
# I've found that much of my time is spent working with programs that support
# some many of the following actions.
# Supported verbs:
#   source:  s
#   install: i
#   test:    t
#   build:   b
#   list:    ls
#   shell:   REPL
#
# Commentary:
# Ideally a file like this would be either unnecessary in the case of a fully
# embraced Emacs workflow or compiled from some high-level language like
# Elisp.

# Adding this to support tramp.
