## @testcase (support) NPE with -argfile foo.lst with "*.java"

cat<<EOF
## input variants
command line:  [ [-argfile | @] X <fileRef>{lst} ]...
fileRef:       [[local | relative | absolute] X [DOS|Unix|Mac]]
file line:     [ option | [@<fileRef>{lst} | <fileRef>{java|aj}] ]
option:        ajc options
refLocality:   [cwd | argfile]

## white box
- @, -argfile delegate to same file-creation method
- direct locality matters: null used for for locals and..
- indirect locality matters: referent varies

## design
-- structure
- invocation
  - could set up as unit tests of ConfigParser.java
    - if so, have also to test delivery to ajc? e.g., do package names
      get calculated correctly under different path variants?
      Probably not an issue now, but perhaps later when source-path
      searching is enabled.
  - could invoke ajc.Main programmatically - can ajc be run repeatedly?
    -> might be easier/safer to script, uncover [bash, DOS,...] shell quirks?
-- test case variants
- command-line 
  - test options
    - ajc
    - esp. multi-flag (-source 1.4) - separate lines?
    - VM/Javac?
  - @, -argfile is independent
  - test 0, 1, 3 on same line, interspersed
  - error: @java file, unflagged arg file
- fileRef depends on locality:
  - parm file: CWD, relative-up, relative down-up, absolute, wrong \/:
    - relative and absolute traversing through directories with
      spaces in them (not in package-named directories)
  - file line: same, with * variants 
    - * variants: [*.java | *.aj] [ empty | 1 | n>1 ]
- fileRef also depends on indirection path:
  - add traversal cases
    - 1-2 levels of indirection
- need to think about whether indirection depends on locality reference
  i.e., whether 1-2 levels of indirection need to be through
  all locality types (CWD, relative...)
- basic argfile
  - options
  - files
  - @ref
  - comments
  - empty lines
  - *.java, *.aj references - re

## implementation
- Source tree 
  - minimal, star, maximal: all need each other to compile
  - some in default package, others in named packages
  - some do not share the same source base (or file system?)
  - files:
  Minimal:
  src/
    Main.java
    pack/Main.java
  Star:
  star/
    Main.java
    empty/
    many/One.java
    many/Two.java
    
  Maximal:
  src1/
    Src1DefaultMain.java
    pack1/Src1Pack1Main.java
    pack2/Src1Pack2Main.java
  src2/
    Src2DefaultMain.java
    pack1/Src2Pack1Main.java
    pack2/Src2Pack2Main.java
