The svn.a script can be used to checkout the ParPCx project as follows:
svn.a checkout acro-parpcx
See the Subversion Documentation for further detail about using svn more directly. The Acro subversion repository supports anonymous checkouts, so you should not need a password for this command.
Acro can be configured using the standard build syntax:
cd acro-parpcx ./setup autoreconf -i -f (Only required if acro-parpcx was checked out with svn) ./configure make
The setup command bootstraps the configuration process with files from the bootstrap directory. This command also supports an alternate configure/build mechanism that archives and analyzes the output of this process (see the Setup Documentation).
