=head1 NAME
LocalModInstall - Install Perl modules locally (into your home directory)
=head1 SYNOPSIS
perl -S LocalModInstall.pl
make
make test
make install
=head1 DESCRIPTION
Install the "LocalModInstall" package using the usual incantation
perl Makefile.PL
make install
or move the file "LocalModInstall.pl" into one of the directories in your
C<$PATH> and make it executable ("C<chmod a+x LocalModInstall.pl>").
Then use
perl -S LocalModInstall.pl
instead of
perl Makefile.PL
whenever you want to install a module locally.
After that, use
make
make test
make install
as usual.
The script "LocalModInstall.pl" will print out the correct settings
to use for the "use lib" statement in your scripts or the "PERL5LIB"
environment variable, as well as the "MANPATH" environment variable.

lib(3), perlfaq8(1): "How do I keep my own module/library directory?"
=head1 VERSION
This man page documents "LocalModInstall" version 1.0.
