#!/bin/bash
# generates alias files for different operating systems and shell scripts.
+# or really, mainly for bash these days, on linux. but we also run under
+# msys and cygwin to some degree.
#
-# This script generates command alias definitions for a variety of different
-# shells. The "common.alias" file is used in all of the generated
-# files as a base set of generally useful aliases. Then the appropriate
-# shell's specific aliases are added in; these are named after the shell that
-# they support, e.g. "sh_aliases.txt" is used with the sh and bash shells.
-# The third component of the file is a set of aliases generated automatically
-# from the names of all the shell scripts in SHELLDIR.
+# The "common.alias" file is used in the generated aliases file as a base
+# set of generally useful aliases. Shorter aliases based on any scripts
+# we can find in the feisty meow script hierarchy are added in as well.
#
-# Additionally, if a file named "c_common_aliases.txt" is found in the
-# $SHELLDIR/custom directory, then it is added in after the other alias files
-# and can override any existing aliases or provide additional local aliases.
-# This file is not included with the YETIcode scripts, since it is intended
-# to be provided by individual users.
-#
-# Further, if any other shell-specific alias files are found mirrored under
-# the custom folder, they are pulled in as overrides for that kind of shell.
-# For example, there is a sh_aliases.txt in the scripts directory for sh,
-# but if there's also scripts/custom/c_sh_aliases.txt, then that will be
-# plugged in as well.
+# If any other alias files are found in the scripts/custom folder, they
+# are pulled in as additions and overrides for the basic feisty meow command
+# set.
