* Fix shifting over `--`: don't throw errexit
Fixes#21
* Add error trapping (including Ctrl-C) info to FAQ
Closes#47
* Add backtracing to help localize errors
- Fixes#44
- Backtracing is turned on when the debugging `-d` flag is passed,
otherwise backtracing function defined but signal trap not set.
- Update main-help fixture due to moving trap
* Untabify main.sh
Might be a controversial move, but I loath tabs...
* Add checks for tab chars and trailing whitespace
- Update poor-man's style enforcement script to check for these
violations
- Better document style guidlines in README with small tweaks
* Add a magic variable to indicate if being source
if `__i_am_main_script=1 #true` then `main.sh` called directly
Fixes#45
* install shellcheck from debian sid repository
* cleanup acceptance shell script
use a uniq temp directory and cleanup
make sure commands we use/need are installed
* shellcheck main.sh
* shellcheck example.sh
* shellcheck test/acceptance.sh
* brace all variables, used [[ instead of [
turn off colors if NO_COLOR is "true" or TERM is not "xterm*" or STDERR
is not connected to a terminal, but ignore TERM and STDERR if NO_COLOR
is set to "false" explicitly.
Fixes#69
turns out that the README.md explains that "... licensed under MIT ...
the LICENSE does not have to be bundled as long as ..." but the scripts
themselfs don't mention any license.
fixed that by adding a one line mention of the used license and the two
lines explaining that the header comments have to stay intact.
