Archive Header Standard

Every source file carries a standard comment header. Format varies by language but fields are consistent:

C / C++ / Java

/*
  name      <name>
  type      <category>
  cve       <CVE or —>
  year      <year>
  os        <target os>
  authors   <original authors>
  source    <where this was obtained>
  archived  krisyotam
  notes     <one-line context>
 */

Python

# ------------------------------------------------------------
# name      <name>
# type      <category>
# ...

Shell / Batch / VBS follow the same pattern using their respective comment syntax (#, ::, ').
