=head1 NAME
cointoss
=head1 VERSION
0.12 (2018-07-03)
=head1 SYNOPSIS
cointoss [B<-p> success_probability] [B<-b> trials] [B<-g> how_many] [B<-s> seed] [B<-1>]
cointoss [B<--help> [ja] ] [B<--version>]
=head1 DESCRIPTION
Generates random numbers obeying Bernoulli and a binomial distribution.
=head1 OPTION
=over 4
=item B<-b> N
The number of trials for a binomial distribution. It is the Bernoulli distribution when N=1.
=item B<-g> N or B<-g> N,N
How many random numbers you want. Given N,N or NxN form, a random matrix will be yielded.
=item B<-p> N
The success probability for the binomial distribution.
=item B<-s> N
The random seed. The residual divided by 2**32 is essential.
=item B<-1>
The secondary information such as the random seed used will be suppressed.
=item B<--help>
Shows this online help manual.
=item B<--help ja>
Shows the Japanese online help manual.
=item B<--vesrion>
Shows the version number of this program.
=back
=head1 HISTORY

ベルヌーイ分布もしくは二項分布(binomial distribution)に従う乱数の生成。
オプション:
-b N : 二項分布の試行回数(整数)。未指定なら1(ベルヌーイ分布に従う乱数が生成される)。
-g N1,N2 : N1行N2列の行列の形で出力。横方向はタブ文字区切り。,の代わりにxの文字でも良い。
-p N : 二項分布の成功確率(0以上1以下の数)。未指定なら0.5。
-s N : 乱数シードの設定。再現性を確保するため。Nの2^32(=約4.3億)による剰余がシードとなる。
-1 : 2次情報の抑制。通常シード情報などは標準エラー出力で色つきで出力されるがそれを抑制する。
--help : この $0 のヘルプメッセージを出す。 perldoc -t $0 | cat でもほぼ同じ。
--help opt : オプションのみのヘルプを出す。opt以外でも options と先頭が1文字以上一致すれば良い。
--version : バージョン情報の表示。
開発メモ :
* -g で Infも指定可能としたい。poissonコマンドを参照。ただし、速度比較をせよ。
