=head1 NAME
B<legacy_blast.pl> - Convert BLAST command line invocations from NCBI C
toolkit's implementation to NCBI C++ toolkit's implementation.
=head1 SYNOPSIS
legacy_blast.pl <C toolkit command line program and arguments> [--print_only]
[--path /path/to/binaries]
legacy_blast.pl [--version]
legacy_blast.pl [--help]
=head1 OPTIONS
=over 2
=item B<--path>
Use the provided path as the location of the BLAST binaries to execute/print
(default: /usr/bin).
=item B<--print_only>
Print the equivalent command line option instead of running the command
(default: false).
=item B<--version>
Prints this script's version. Must be invoked as the first and only argument to
this script.
=back
=head1 DESCRIPTION
This script converts and runs the equivalent NCBI C toolkit command line BLAST
program and arguments provided to it (whenever possible) to NCBI C++ tookit
BLAST programs. Note that to specify options to this script they B<MUST> use 2
dashes to prefix the options B<AND> be listed at the end of the command line
invocation to convert.
=head1 EXIT CODES
This script returns 0 on success and a non-zero value on errors.
=head1 BUGS
Please report them to <blast-help@ncbi.nlm.nih.gov>
