R-beta: updating the library index / overriding compile options

[Albrecht Gebhardt]

Would it be possible to include a new command in the ${RHOME}/etc path, which
updates the Library index (Rd and html) via  "R LIBINDEX".

I need it because I use RPM to manage three different R installations (at home,
at the institute and in the seminar rooms). I put all libraries into several
packages, so it is easy for me to update a single library at all these
different places. 

But after installation or removal of a library via rpm the help indices have to
be updated.  A call like "R INSTALL +help" in the post/pre install/uninstall
script calls also "make" in the library source trees, which is unnecessary (and
may even fail, e.g. because of a missing Fortran compiler). 

The following script does exactly what I want (I don't know if it will work
for library directories other then $RHOME/library):
##############################################################################
#! /bin/sh

# ${RHOME}/etc/LIBINDEX for updating the library index
# Usage:
#       R LIBINDEX [lib]
#                



lib=${1:-${RHOME}/library}
test -d ${lib} || exit 1;
lib=`cd ${lib}; pwd`

rm -f ${lib}/LibIndex 

echo updating LibIndex ...
for pkg in `ls -d ${lib}/*`; do
    if test -d ${pkg}; then
        if test -f ${pkg}/TITLE; then
#          echo " adding entry for library" ${pkg##*/}
           cat ${pkg}/TITLE >> ${lib}/LibIndex 2> /dev/null
        fi
    fi
done

echo updating HTML index ...

${RHOME}/etc/build-htmlpkglist

echo "DONE"
##############################################################################

It would also be good, if some of the compile options could be overridden in
a "R INSTALL ..." call. Especially I'm using GNU Fortran when compiling the base
R disribution, that means $src is set to "src". But g77 fails on some of the
libraries. So I want to do "R INSTALL +docs src-c libname" for this library
which sets $dir to "src-c".

I would propose the following patch to includes these two options
("src" or "src-c") into "R INSTALL":

I'm not sure if this is the best way. Any other ideas?
