The HP aC++ Online Programmer's Guide contains full documentation. (See Chapter 3 of these release notes for access instructions.).

The HP aC++ Online Programmer's Guide has been updated from HP CDE format to HTML format viewable with your HTML browser. For details and access instructions, see Chapter 3 of these release notes under Online Documentation.
Standards based features include the following:
- covariant return types (except for covariant return types with multiply inheriting types)
- Koenig lookup
  Note: You must specify the -Wc,-koenig_lookup,on option.
.The -I- header file option invokes view-pathing. This option overrides the default -I<directory> option header file search path.
Additional options for verbose compile and link information:
- +dryrun - Requests compiler subprocess information without running the subprocesses.
- +time - Requests subprocess execution times.
- -V - Requests the current compiler and linker version numbers.
+M[d] and +m[d] options to output the header files upon which your source code depends in a format accepted by the make(1) command.
+We option allows you to selectively interpret a warning or future error as an error.
The __HP_aCC predefined macro identifies the HP aC++ compiler.
At this release, the +inline-level option defaults to 1. In the prior versions, A.01.09, A.01.12, A.03.05, A.03.10, the default was 0, no inlining was done (the same effect as the +d option).
This change was made based on customer feedback regarding object file size and runtime performance.
